1
These are mealworms, and they're known for their ability to eat almost anything.
2
But what if you put 10,000 mealworms on a whole watermelon?
3
How quickly would they completely eat it and turn it to mush despite its massive size?
4
Yeah, I don't know, so that's why I bought 10,000 mealworms.
5
Yeah, this is the most nastiest thing I've ever done, but it'll also be one of the most satisfying things I'll ever do on the channel.
6
Okay, well, I got the watermelons right here, but I actually first just kind of want to put this
7
piece of bread in here to see how quickly these mealworms will start to devour it.
8
So yeah, I put the bread inside and as you could probably imagine, the mealworms wasted no time to start swarming this thing and of course, they then started to consume it.
9
If you pay attention to right here in specific, you can see how they just devour a massive hole right through the center of the bread.
10
If they're doing this to the tiny piece of bread, imagine what they do to the full watermelon.
11
Anyways, literally after only four hours this bread was hollowed out with mealworms
12
and just had holes all over it
13
but this is literally nothing compared to the other time lapses
14
i'll be showing off in the video i have tons of
15
stuff planned ending with the final 10 000 mealworms versus the whole watermelon
16
but don't think the stuff before is boring
17
because we're gonna be starting with leeches yup you heard
18
that right for the first time lapse i'll be recording i went
19
and bought five big leeches yep leeches usually live in the wild
20
and grab onto unsuspecting prey to basically just suck the blood
21
out of them well since i have five of these leeches
22
and they're in captivity it's gonna allow me to get some
23
insane time lapse footage of them sucking the life out of
24
a food object as the leeches get bigger it should be pretty cool now
25
if you watch my video about keeping pet leeches you'd know
26
they basically like to spend all their time under the water
27
so that's why i'll be setting up an aquarium for this test
28
and then quickly i'm just gonna fill up this tank with this
29
so i can go ahead and put the leeches inside so we can get this test started.
30
So yeah, I put each of these five leashes inside and I put a lid on top so they didn't escape.
31
And immediately you can kind of just see how they all just start swimming around under the water, just sort of like how snakes do.
32
Yeah, it's kind of weird, honestly, but once they want to stop swimming, they'll go up to the glass and just grab onto it using the end of their bodies basically as a suction cup.
33
It's actually pretty cool.
34
Anyways, for the food I'll be feeding these guys, it's this piece of beef liver.
35
Well, all right, why don't we just drop this slimy nastiness into here
36
and see how long it takes for these leeches to get absolutely massive.
37
And so step one was to actually get the leeches to bite onto this piece of meat, which is pretty easy.
38
You basically just pick up the piece of meat with tweezers
39
and start bringing it up to the leeches' faces until they grab onto it.
40
So yeah, I just went around and picked up all the leeches onto the meats.
41
But if you couldn't tell, the water quality got super bad because of the beef liver.
42
So I decided to actually let the leeches eat the beef
43
liver out of the water since in the wild that's actually how they prefer to feast
44
and while a couple of the leeches kind of detached from the piece of meat
45
and started to run away three of the leeches actually did stay on it
46
so i could watch as they started to eat you can literally see them contract their throats in
47
and out as they basically use their teeth to grind the meat up
48
and then they suck it up like a smoothie up into their bodies
49
but things actually did not go to plan
50
because out of nowhere this leech decided to detach from the piece of meat
51
and then he just started to slither away randomly then the other two leeches decided to detach too
52
and this guy decided to just burrow into the piece of meat
53
and this one just slithered away hey at least you got to watch him eat for a little bit
54
but this is why i love time lapses you just capture random interesting stuff like this
55
but even these leeches are nowhere near as interesting as the time lapse coming up later
56
because the time lapses get cooler as the video progresses
57
so that's why for our second time lapse
58
so we're gonna be recording flesh eating beetles yes you heard
59
that right flesh eating beetles and and they're called that because they're beetles that eat flesh.
60
And well, let me show you why that is so cool.
61
Now, as you can see, there's some actual flesh-eating beetles in here, but most of the things in here are still in their larva stage, which means they're actually even more hungry than usual.
62
And you see, these insects are cool
63
because they can literally just eat the flesh off of animals to the point where they only leave the skeleton bones behind.
64
So yeah, I'm going to try and record a time-lapse of that.
65
And I've got thousands of flesh-eating beetles in here to the point, if I put my finger in there, it would probably turn into a skeleton.
66
Actually, you know what?
67
I wonder what would happen if I put a piece of dog food in there.
68
Hey, I guess let me get a quick time lapse real quick.
69
So I put the dog food in and oh guys, all I'll say is things are about to get interesting with these beetles.
70
But as you could probably imagine, buying all these crazy bugs and worms is extremely expensive and I've been needing to manage a lot of money.
71
So that's why I'm glad today's sponsor is Chime.
72
If you didn't know, Chime is the number one most loved banking app that millions of Americans, including me, use to help people bank smarter and have their money work harder.
73
But specifically, Chime was wanting me to tell you guys about their high-yield saving accounts, which I'm going to be honest is easily my favorite feature about them,
74
because they offer up to a whopping 3.5% APY on your savings, which is over 8 times higher than the national average of 0.4%.
75
To put that into numbers, that's an extra $310 you'd earn with Chime if you had $10,000 in savings.
76
Yep, so you remember how expensive I was saying all those mealworms were?
77
By literally just having my money saved in my Chime high-yield saving account, so my money grows for itself, and those worms will essentially just end up paying for themselves.
78
Thanks, Chime.
79
But don't think Chime is just a saving account.
80
Like I said, it's an entire banking app that has so much more to offer.
81
Thankfully, there's no monthly fees, and they won't charge you if you accidentally overdraft up to $200.
82
And on top of that, you can get paid up to two days early.
83
It's super easy to sign up, and the best part is right now they're offering up to a $350 bonus with a new Chime account using my link.
84
So if you guys aren't already using Chime, either scan the QR code that's been on the screen, or check out my top link in the description for a smarter, simpler way to manage your money.
85
Anyways, let's get back to the flesh-eating beetles.
86
And if you were wondering, it didn't take them very long for them to start swarming this piece of dog food.
87
You see, these are dog treats that I buy for my dog Jet, and they're made out of the top quality real beef ingredients, which of course Jet loves.
88
But that also explains why these flesh-eating beetle larvae were also loving it.
89
Anyways, it was pretty crazy how after just a few of these beetles latched onto the dog food, Pretty much all of the beetles soon followed behind until literally
90
this piece of dog food was literally like just not a piece of dog food anymore.
91
This is just a living piece of flesh eating beetle at this point.
92
Yeah, there's just so many on here.
93
Oh my gosh, bro.
94
What?
95
These guys are so hungry.
96
So yeah, I shook them all off because if you remember, the main reason I got these beetles is
97
because I actually want to see if they could turn an animal into a skeleton by just eating its flesh.
98
And I don't want them to get filled up on this.
99
But anyways, considering this piece of dog food was only in there for like 10 minutes, the beetles made a pretty decent amount of progress by chewing a bunch of tiny little chunks out of it.
100
Anyways, for the main course on feeding these guys, I've got a duck head.
101
Yeah, and we're gonna see if they can turn it into a white duck skull.
102
But yeah, don't worry guys, I didn't do this to the duck.
103
I actually just bought this at the pet store.
104
Apparently they're dog food.
105
Jack, can you give this a taste test?
106
You think the flesh-eating beetles, you think they're gonna like it? um yeah he's licking it i think he likes it
107
so since it passes the jet taste test i wasted no
108
time to put this into our tank let's see what these bugs do now immediately things were pretty interesting
109
because many of the beetles of course were drawn to this nasty duck head
110
and pretty much all of the beetles started to gather at
111
the base of the head these guys were all slowly chewing away at the fur of this duck head
112
and it was cool
113
because you could gradually see the group of flesh eating beetles move up along the side of the duck head
114
and they were even eating it so much that they ended up knocking it over.
115
Eventually, it was so nasty because the beetles had just completely swarmed the head
116
and were crawling in and out different parts of it, like the hole in the beak.
117
And after leaving this in here for a full 24 hours, you can just see how much they chewed through all the fur, and just how nasty this is.
118
But the real damage was done on the bottom of the skull, where it was completely chewed through.
119
These are the literal bones of the duck skull, and this is just straight up so disgusting.
120
This looks like a zombie duck head at this point.
121
Oh my gosh, this smells so bad, you guys don't even know.
122
But dang, check this out.
123
I'm actually kind of surprised.
124
This didn't just like turn a completely white skull kind of color.
125
Because I know these beetles sometimes do that.
126
But I guess it makes sense.
127
This is just kind of dog food.
128
But I would call it a success.
129
I mean, look at how destroyed this thing is.
130
Anyway, so these guys will definitely make a very interesting addition to my pet collection.
131
Alrighty, we're almost at the final 10,000 mealworms versus watermelon test.
132
But quickly, I'm excited to show you guys time lapse number three, which is an alien creature digging.
133
Yep, you know how some people set up their ant colonies
134
and 2D ant nests to get footage of them digging out those tunnels along the glass?
135
Well, this alien creature is actually able to do the same exact thing.
136
Let me show you how.
137
Yeah, so this thing's called a vinegaroon, and it's the same one from a few videos ago on my channel.
138
But you see, I call them an alien because, let me just look at them, they look extremely weird, and they have these claws at the front of their body that actually allow them to dig.
139
Yup, and for this guy, as you can see, I filled this tank up with a bunch of clay.
140
But if you look, I actually left a hole on the side of the glass empty.
141
That way, when I go and fill this place up with dirt, the vinegroom won't be able to make a hole anywhere in this dirt, other than that hole I made in the clay right on the side of the glass there.
142
Now anyways, after getting the dirt in, I wasted no time to put the vinegroom inside.
143
Now immediately, this alien creature wasn't exactly super interested in digging.
144
He was kind of just trying to climb out.
145
But you see, that's
146
because there's actually a few things I have to set up in here to make this guy want to dig quickly.
147
First of all, I put this water dish in here, and then I started to use my finger to dig out a little tunnel under the water dish.
148
Now when the vinegaroon comes over here, he'll find the little entrance to the burrow I made, and when he's ready to dig, he'll know where to start.
149
So guys, I just went and set up my time-ups camera in another room, so we could observe what these creatures do when no one's watching.
150
And yeah, during the first few hours, since it was technically still day, you can see he was very active amongst the top section, still trying to escape.
151
But the second it hit nighttime, this dude went down to the burrow section, and he started to dig up like a straight up drill.
152
Nah, let's see that on an instant replay.
153
That's actually pretty cool.
154
You can literally see the pile of dirt up here grow as the vinegaroon digs out all the dirt from the tunnel.
155
I think this is some of the clearest footage ever caught of these creatures digging.
156
It's pretty cool to watch.
157
Well, dang, now that this guy dug this tunnel, you're probably wondering why they actually make these tunnels.
158
Well, they actually make them to hunt.
159
And well, I got a cricket right in here.
160
Let's drop this thing in.
161
And so after I dropped the cricket in, he started to walk around the top area.
162
But little did he know, the vinegaroon was right under his feet, waiting in the burrow for food to walk in.
163
And a little bit later, the cricket did just that.
164
He started squeezing through the opening that was dug out the night before.
165
And he went in deep enough to where the vinegaroon was sitting.
166
I know it got super foggy in here when I brought it to my recording area, so it's kind of hard to see, but the vinegroom started to attack the cricket, and he started to chase him out the burrow.
167
The cricket tried to escape, but it was no use because the claws of the vinegroom are just too strong.
168
And I know you guys can't really see it well in this footage, but I can assure you, the cricket is no longer with us, to put it lightly.
169
Dang, that was cool.
170
But I'm gonna go and move this guy back to his original enclosure I built in the original video.
171
Well guys, it's finally time to do our final time lapses with the 10,000 mealworms.
172
Okay, I'm not going to waste any time and I'm going to record some stuff right away.
173
But before we do the watermelon, I actually want to start with something a lot more interesting.
174
This thing.
175
Yeah, this is literally a piece of styrofoam.
176
And you're probably wondering right now, what the heck, Terra green why are you feeding this to the worms well it's
177
because mealworms have an absolutely insane special ability and it's actually
178
that they can somehow digest styrofoam yeah talk about the lamest special ability ever
179
but i just had to get a time up showing this off
180
and immediately these dudes started to completely climb all over the
181
styrofoam completely covering it i don't know why mealworms are one of the only animals that can eat styrofoam.
182
It's honestly kind of weird.
183
And the craziest part about this time lapse is if you look right down here, you can literally see the moment when the mealworms decided to start chewing a massive hole through the side of the styrofoam.
184
So they could literally crawl inside to eat more.
185
It's super cool.
186
And anyways, after leaving the styrofoam in here all night, I shook off all the mealworms so we could see the damage that was done.
187
And holy look at this thing.
188
First of all, that hole the mealworms shoot through the side is nasty and it's still filled to the brim with worms.
189
Then just this whole top part has bite marks all over it.
190
And this thing is probably hollowed out and just filled with worms.
191
Nah.
192
And yeah, if you're wondering about the other pieces of styrofoam, basically the exact same thing happened to them and they got obliterated.
193
It's safe to say these mealworms are hungry.
194
Now, I think it's about time we get out the watermelon so we can do the final time lapse.
195
And I got a knife here so I can go
196
and cut this thing up so we can reveal the nice juicy red part.
197
So yeah, that's exactly what I did, and I just put the watermelon straight into this tank so we could get this test started right away.
198
Now, you already know, the mealworms started to, of course, climb all over the watermelons right away.
199
Mealworms love watermelons because, of course, they're super sugary and sweet, but they're also made out of 92% water, meaning the mealworms can just get super hydrated.
200
Now, it's so crazy because you can see how nice and bright red this watermelon is now.
201
Well, it only took a couple hours until
202
that bright red completely started to fade as thousands of mealworms started to climb all over the watermelon, nibbling tiny little pieces out of it.
203
And yeah, this all happened in the time span of only 12 hours.
204
Yeah, I literally just left this overnight.
205
Okay, I just checked on this for the first time since waking up.
206
And first of all, this smells absolutely disgusting.
207
But look at this.
208
This was a bright red color like 10 hours ago
209
but it's like completely rotting because of what these mealworms are doing to it.
210
This is nasty and they're making all these tiny little holes in it.
211
Nah.
212
Anyways, I moved the tank to the floor to continue the rest of the time lapse.
213
But as you can see in this footage, as I continued recording, the mealworms weren't nearly as interested in the watermelon.
214
Pretty much none of them were even eating it anymore.
215
I mean, it does look pretty rotten to be honest, so I guess it would make sense to why they don't want to eat it.
216
But yeah, I decided to just stop the time lapse since they weren't eating it anymore
217
and I came back 24 hours later so I could see the full results of what the watermelon looked like.
218
What the heck?
219
This is so nasty.
220
Is that mold growing on the watermelons?
221
Oh my gosh.
222
But actually to my surprise, when I took a look under the watermelons, there was massive holes chewed through the green shell part.
223
And like this watermelon here had so much chewed through this part.
224
So yeah, I guess the mealworms really were eating the watermelon, but I guess it just wasn't showing up on the time-lapse
225
because it was happening under where we could see it dang that's actually insane
226
that they could eat so much anyways hopefully you guys learned something new
227
or were entertained by the time-lapse as I showed you in this video
228
and about these 10,000 mealworms well I'm gonna have to see
229
if I can get these donated to a pet shop
230
or something anyway since this is the last video I'm posting
231
in 2025 I just want to give a massive special thanks
232
to everyone that's been watching the channel this year we've seriously grown so much and we've just posted so many fun
233
and cool videos.
234
So seriously guys, thank you.
235
I actually appreciate it a lot.
236
And of course, thanks again to Chime for sponsoring this video.
237
Remember to grab the up to $350 bonus to start the new
238
year off right with Chime by scanning the QR code on the screen or checking out the top link in the description.

¿Qué es la Técnica de Shadowing?
Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
