Shadowing Practice: 1,000 Flies vs. Venus Fly Trap - Learn English Speaking with Video
Creando lección...
1
This is 50 Venus fly trap plants,
2
and in this video, I'm gonna put 1,000 flies in the same container as them.
3
Will the sheer number of flies trick the traps causing them to close,
4
or are the flies just simply cooked?
5
Yeah, I don't know, but that's why I bought this.
6
This is 1,000 fly larvae.
7
Yeah, might look extremely nasty,
8
but over the next week,
9
as long as I feed them food,
10
they should all turn into flies so I can do this test.
11
So while we wait for these guys to turn into flies,
12
obviously I have all of these Venus fly traps.
13
But I also have tons of other carnivorous plants that you may have never even seen before.
14
Meaning I'm going to be able to do tons of different tests in this video.
15
It's going to be super cool.
16
And for test number one,
17
I want to show you guys the smallest Venus fly traps.
18
Now I know it may sound stupid,
19
but I promise you how they work and catch insects is actually really insane.
20
Let me show you how they work.
21
And yeah, it's not a joke how small these things are,
22
because when compared to normal Venus fly traps,
23
the jaws are about 10 times smaller.
24
In fact, they're kind of cute to be honest.
25
But since these are minuscule,
26
the normal prey I feed in my videos is not going to cut it.
27
Yeah, sorry cricket, you get to live another day.
28
That's why instead, I got literally the smallest thing available.
29
These are flightless fruit flies,
30
which if you've seen my channel before,
31
you know they're pretty much the most useless animal.
32
Because seriously, bro, how are you a fly that doesn't have the ability to fly?
33
That doesn't make any sense.
34
But anyways, I put the smallest Venus fly traps in the testing enclosure,
35
then I put one of these flies inside to see if he'd get caught.
36
Start the timer.
37
Now this fly didn't waste any time,
38
because it immediately walked straight up to one of the Venus fly trap pots,
39
and then started to walk all over the tops of the jaws.
40
Absolutely risking his life.
41
You may already know this,
42
but normal Venus fly traps work by having these super tiny trigger hairs inside of them,
43
that when a bug or something touches them, it snaps shut.
44
But these traps are obviously the smallest in the world.
45
Because of that, they have extremely small trigger hairs.
46
And I'm talking so small that if I zoom in like 100x on this footage,
47
they're so thin, my camera can't even pick them up.
48
And I guess the trigger hairs were quite literally so thin
49
that every time this flightless fruit fly walked inside the jaw of a trap,
50
the jaw didn't close at all,
51
and the fly was able to just walk out.
52
I mean, it kind of makes sense.
53
These flightless fruit flies weigh about 0.0003 grams.
54
So yeah, I guess the traps quite literally can't even be triggered by how light their weight is.
55
Yeah, clearly the fruit flies aren't gonna work.
56
So instead, I got the world's smallest cricket instead to test.
57
Let's see if this works any better.
58
And oh boy, let me just tell you,
59
things were a lot more interesting this time around.
60
Because once again, the cricket walked straight up to one of the trap pots
61
and started climbing all over the tops once again.
62
But this time, quite literally within 30 seconds,
63
the cricket happened to put his face up to the lip of one of the Venus fly traps.
64
You may also already know this,
65
but these plants produce a special kind of nectar around the lips of their jaws to lure insects in like this cricket.
66
And you can see it was working pretty well because this cricket was just absolutely slurping this nectar up.
67
But he was getting a bit too distracted because he then stepped into the trap,
68
probably stepping on the micro trigger hairs,
69
which then caused the jaws of it to close.
70
But the cricket was too fast and he was barely able to make it out with his life.
71
Dang, that was a close call,
72
but you can see how quickly that can all happen.
73
And yeah, don't worry guys,
74
because there's only a few minutes later when the cricket did the same exact thing.
75
He walked up to another jaw, walked straight into it.
76
And yeah, this time the trap closed on him while he was starting to walk out,
77
leaving half of his body now sticking out of the trap.
78
Even though these are the smallest venus fly traps in the
79
world they trap insects nearly just as well as the fully grown ones it's pretty interesting
80
and yeah while i wait for those 1 000 flies to hatch
81
so we can do the final test in the meantime i want to show you some other insane carnivorous plants
82
that you may have never seen before with the second one
83
being sundews yep everyone knows what venus fly traps are
84
but not everyone knows what a sundew is
85
but they're actually pretty cool let me show you what they do So obviously like fly traps,
86
sundews are also a carnivorous plant.
87
Except instead of having jaws,
88
it has these long stems with these little red hairs on the top of them.
89
But on each of these little red hairs is a special kind of sticky glue it produces.
90
That will make it so when a fly or any other insect touches it,
91
it gets permanently stuck because of how sticky it is.
92
And when an insect gets stuck on here,
93
the trap does something insane to be able to consume the insect.
94
Which I'll show you very soon when it obviously traps an insect.
95
So yeah, I got multiple of these sundew plants,
96
and I even got this slightly different kind of sundew called an octopus plant.
97
That will be cool to see if this can catch any insects as well.
98
So let's get these in the testing chamber.
99
And for this, I think I'll be using a cricket once again,
100
because they're literally perfect.
101
They can just climb up the side of the stems and yeah, just get stuck.
102
This should be fun to watch.
103
Let's put this dude inside.
104
So yeah, once again, I just started with one of these guys.
105
But if this guy gets caught fast,
106
I'll be adding way more inside of here.
107
Anyways, this cricket for the first minute kind of just wandered around the walls of the enclosure,
108
but it wasn't long until he started heading towards the sundews.
109
Now you see, the sticky glue that this plant produces is actually a type of nectar,
110
which smells and tastes great to the insects.
111
So yeah, just like how Venus flytraps lure insects in with their nectar,
112
these traps do the same thing,
113
because this cricket then decided to start climbing up the stem.
114
The only thing is though,
115
that he ended up stopping right before the sticky part,
116
and that's actually because of his antenna.
117
You see, crickets have these pretty long antennas that help them navigate and detect danger before running into it.
118
And this guy's antenna actually ended up getting stuck in the sticky nectar part.
119
But using its mouth, it was able to pull the antenna back
120
and then started to lick all the nectar off of it.
121
Yeah, and I'm not kidding.
122
This cricket really just sat here for like 30 minutes,
123
constantly licking his antenna, then putting it back into the sticky nectar,
124
and then licking it back up.
125
He was kind of outsmarting this carnivorous plant and just getting its nectar for free.
126
So I'm not gonna lie.
127
I just tried to push him towards it with my tweezers
128
since he clearly wasn't gonna do it on his own And uh,
129
yeah, he just kind of ended up falling off Yo, what the heck?
130
I was just trying to record that cricket and I just realized there's a jumping spider in here Do you see that?
131
It's on the little octopus plant Is it stuck?
132
Yeah, this jumping spider just happened to wander into this enclosure
133
by accident I guess he was just living somewhere in my house But since he was here,
134
I figured i'd just watch him to see if he would get caught by the traps And pretty quickly,
135
he started to climb the stems of the trap and got up to the sticky part.
136
Um, but yeah, he was kind of too smart for this trap too,
137
and turned around the second he realized it was sticky.
138
But it was pretty cool to watch this guy just jump around the plants.
139
However, he never really ended up getting trapped,
140
and he ended up just climbing out of the enclosure.
141
All right, guys, I'm not gonna lie,
142
this cricket, I've been trying to record him getting eaten for like two hours now.
143
And every time, right before going on the sticky part,
144
he just stops and cleans his antenna.
145
And yeah, he just turns around and never actually goes on the sticky part.
146
He's too smart for this.
147
So yeah, let me take this guy out.
148
Instead, I actually just got out the flightless fruit flies again,
149
because apparently this is actually Sundew's favorite insect.
150
And yeah, I just dumped a few on the sand,
151
and it wasn't long until some of them started to climb all over the stems
152
and eventually started getting stuck all over the different sticky parts.
153
I even went
154
and just dumped a crazy amount of these flies all over
155
the top of the sundew plants to show you guys exactly how cool sundews really are.
156
Because obviously, now you can see the sticky parts of the plants are just completely covered in flightless fruit flies.
157
Now, if you're wondering how this plant actually eats the flies,
158
well, this footage shows how.
159
As you can see, it uses each of its red hairs to basically curl around the prey.
160
And once all of those curl around it,
161
the stem itself also starts to curl around the prey.
162
This will basically ensure the fly has a 0% chance of escaping while the plant releases basically an acid to consume it.
163
Yeah, it's pretty brutal.
164
So yeah, it's pretty cool to see these things work.
165
All these flies are just going to turn into food for these plants very soon.
166
All right, there's still one more major carnivorous plant type that I haven't shown yet.
167
They're called pitcher plants.
168
Yep, this plant can also eat insects.
169
And actually how it does it is probably the most brutal out of all of them.
170
Let me show you.
171
Yep, like I said, these are called pitcher plants
172
and similar to the last plant they have pretty long stems
173
that go up
174
but the difference is this time at the top there's this little trap door leaf thing
175
that if you look is actually covering a hole
176
that leads directly down to a pit of acid at the
177
bottom of the stem yep these traps have this little hole
178
here that's lined with a super slippery nectar on the inside
179
so whenever an insect walks inside they'll slip into the acid at the bottom
180
and yeah and what's really cool is if you actually look inside of this pitcher plant,
181
since it's kind of small and shallow,
182
you can actually see the pool of acid at the bottom.
183
And it actually looks like there's a couple little flies and stuff in there,
184
which it looks like it's actually already dissolving.
185
So yeah, it'd be cool to see some crickets or something following these.
186
Let's test it out.
187
I didn't even need to use an enclosure this time because I knew this was going to be an extremely fast test.
188
Because immediately after placing the cricket on this first pitcher plant,
189
it started to climb along the sides of the red pitcher.
190
As you can see, the inside of the plant is lined with these downward pointing hairs.
191
This is to make it even more slippery and hard to escape.
192
And yeah, it's kind of funny to see how fast this all happens,
193
but the next time the cricket went to the opening of this plant,
194
it straight up just slipped in right away.
195
Nah, this dude had no clue this plant has evolved over
196
millions of years to just be able to eat them this fast.
197
Um, yeah, and as you can see on this footage that I recorded on my phone,
198
he was now just sitting at the bottom of this pool of acid.
199
Over the next few days,
200
it'll dissolve him and turn him into nutrients for this plant to grow even stronger and larger.
201
Nice.
202
And yeah, that's really all there is to these pitcher plants.
203
They're not really the most interesting thing ever,
204
but I actually have some great news guys.
205
Cause if you look in this container,
206
you can see many of my flies are starting to hatch.
207
And that means we can finally start doing some massive scale of Venus fly trap tests
208
and eventually test as many flies as I can against all of my Venus fly traps to see who wins.
209
Let's start very simple though with five Venus fly traps versus a single fly
210
and let's see if this fly can get trapped in under a minute.
211
Now I know you may be thinking,
212
Brat Teregrine, I don't care about one fly, this is boring.
213
Well don't worry because this literally only lasted like 20 seconds
214
because immediately this fly started to crawl up the side of a pot And of course,
215
he made his way immediately into a jaw,
216
triggered one of the hairs,
217
and it closed directly onto him.
218
Yep, flies are basically the one thing Venus fly traps are the best at catching.
219
I mean, they're called Venus fly traps for a reason.
220
Anyways, I got the tank where the final test will be taking place, right here, obviously.
221
And oh, on top, there is a box that I want to show you.
222
There is something really cool in this box.
223
It's these two little drawstring bags.
224
As you can see, they say Terra Pals on them,
225
and that's because Terra Pals is what I'm calling my brand new line of plushies.
226
And in this first limited edition drop,
227
we've released a super cool jumbo snake and a super cute little axolotl.
228
And when you buy this,
229
you don't only get the plushie from inside,
230
but you also get this super cool golden trading card pack that obviously you can open.
231
As you can see here,
232
I got the Axolotl card and this one's actually one of 25.
233
Yep, I've signed 25 of the Axolotl and Snake cards,
234
meaning some of you will get some signed cards that I'll never be signing again.
235
But either way, if you get a signed card or not,
236
I know you guys are going to enjoy these new plushies.
237
Anyways, let's get back to the final flytrap test.
238
And I didn't waste any time.
239
I just got out the flies that I've been hatching.
240
And I put them straight into this enclosure so we could get this final test started.
241
Quickly, I removed the lid and started the timer.
242
Let the test begin.
243
Now immediately a couple of the flies started to fly out of the container
244
and others started to walk out of the sides.
245
Now there was something weird though because while the container had a decent amount of movement in it,
246
only like 10 of the flies were actually leaving the container over the 4 hour time lapse here.
247
Yeah, basically all the flies were staying in there.
248
So I decided to just take the paper towel out
249
that they were all on and try to just shake off as many as I could onto the Venus fly traps.
250
And obviously, this meant that a few of the flies were now scattered all over the traps,
251
and were actually starting to get trapped.
252
But most of them were just being super inactive,
253
barely moving, and not flying.
254
I guess because they were just newly hatched flies,
255
and it takes a while for them to become normal.
256
Yeah, I'm not gonna lie guys,
257
this is kind of a fail.
258
Basically, none of the flies are flying around,
259
and I don't think I'm gonna be able to finish this.
260
But don't worry, because my YouTube friend Fly Trap Films recorded a test with an insane amount of flies,
261
a super similar to this and he wanted me to show you it
262
and you can see he has a venus fly trap plant out
263
and also a bunch of rotten meat in order to attract the flies yeah
264
and it worked really well because instantly tons of flies started to gather around this plant
265
and you guessed it started to get trapped i mean
266
when you have this many flies it's a given
267
that tons are just going to get trapped right away
268
and what's so crazy is that sometimes
269
so many would gather on some of the jaws before they
270
close causing up to six flies to get trapped in the
271
same jaw at the same time what flytrap films himself said
272
that this is the most flies he's ever seen
273
that get caught at once also some bonus footage for you
274
guys hey you remember those pitcher plants from earlier flytrap films
275
also did the same test with a massive pitcher plant to
276
show you guys how effective these things are at catching flying insects
277
and this plant literally just looks like a vacuum cleaner sucking up all the flies
278
which in a way it kind of is
279
because every time a flying insect flaps its wings above the
280
opening in this plant it creates a weird kind of vacuum
281
effect with the wind causing the bug to actually get pulled down into it
282
and yep after not too much time this thing just caught
283
so many flies it was literally just starting to overflow
284
that is probably the craziest performance from a carnivorous plant
285
that i have ever seen thank you flytrapfilms for letting me show you this footage.
286
Make sure to check out more of his videos,
287
guys, if you want to see more like this.
288
His content is so cool.
289
Anyways, hopefully you guys learned something new about carnivorous plants in this video.
290
And remember, guys, check out the brand new Terra Green Limited plushies that just dropped.
291
Remember, I only signed 25 of each of the limited edition trading cards,
292
so make sure to get these soon if you want to get those.
293
All this is available on TerraGreenStore.com.
294
Seriously, guys, thank you for watching the videos.
295
It means a lot, and have a good day.
296
Goodbye.

¿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.
