1
This is an assassin's teapot.
2
It can be used to pour yourself a drink and to pour a drink for your enemy.
3
You can then down your drink to prove that the drink isn't poisoned.
4
There's no poison there.
5
Don't worry about the poison.
6
There is no poison.
7
But then when your enemy takes a drink, they find out that it is poisoned.
8
And by the way, this doesn't require you to spend the last few years building up an immunity to Iocane powder.
9
It works straight off the bat.
10
No preparation required.
11
That's because the Assassin's teapot can be used to pour three different drinks, which I've shown here using three different colored liquids.
12
And by the way, if you plan to poison your enemy, I recommend using liquids of the same color.
13
Do I need to tell the viewers that they shouldn't be trying to poison people?
14
Like legally, just that it would break the flow of the video.
15
Film myself having a fake phone call with a lawyer in which I explain the problem.
16
And so long as I say out loud, don't try to poison people, then that should have me covered.
17
Okay.
18
Click.
19
The way you choose the drink is by sneakily covering up one of these holes.
20
If you cover this hole, you get a blue drink.
21
If you cover this hole, you get a yellow drink.
22
If you cover no holes, you get a green drink.
23
So three drinks in total though actually no four drinks.
24
If you cover both holes you get the null drink.
25
But how does it work?
26
Well you know me
27
if I want to describe how a hydrodynamic mechanism works I like to make a transparent 2d version of it.
28
I'll put a playlist of those videos in the card in the description.
29
First I needed to figure out what was going on inside the teapot
30
and a bit like with the glugl jug the only really sensible way to do
31
that was to hit it with a hammer.
32
So you can see there are two chambers here side by side and they both lead up to the spout.
33
Additionally, one chamber leads up to this hole, the other chamber leads to this hole.
34
For the 2D version, I don't want to put them side by side because then it wouldn't be 2D,
35
but I feel like I can put them top to bottom and it should still work.
36
And here it is.
37
So if I want a blue drink, I cover this hole.
38
If I want a yellow drink, I cover this hole.
39
And if I want a green drink, I cover neither of the holes.
40
And for completeness, here's the null drink.
41
Similarly, I could have a black coffee, or I could have milk, or I could have a milky coffee.
42
So that's how it works.
43
But why does it work?
44
Why is it that putting your finger over different holes causes different liquids to flow out?
45
Well, it comes down to surface tension.
46
It's similar to this demonstration you might have seen before.
47
Look, I can pour water from this bottle, but if I turn the bottle upside down, no water pours out.
48
The trick is that there's a gauze covering the opening of the bottle.
49
So when I pour it like this water can flow out
50
and air can flow in but
51
when I turn the bottle upside down for water to flow out air would need to flow in
52
and for air to flow in surface tension would need to be broken.
53
Here's another example where instead of a gauze there's a small hole.
54
The hole's actually big enough to push a straw up into and it floats to the top of the bottle.
55
It's a really cool trick.
56
You know, strictly speaking, ultimately, it's not surface tension that's keeping the liquid in place.
57
It's air pressure.
58
Like the assassin's teapot and these bottle tricks wouldn't work in a vacuum.
59
So the reason the liquid doesn't fall out of the assassin's teapot
60
when you have your thumb over the hole is because the atmosphere is pushing on it.
61
Atmospheric pressure is holding the liquid in place.
62
And that's counterintuitive.
63
Like you you think, well, the real explanation is that, you know, well, if the liquid did fall out a little bit,
64
it would create a vacuum and the vacuum would pull the liquid back in.
65
But there is no pulling force.
66
There's only pushing force from the atmosphere.
67
It's like when you suck on a straw, it's not the suction that's pulling the liquid up the straw,
68
it's the atmosphere pushing the liquid up the straw.
69
And that's really counterintuitive because you feel like, well, look, that's me doing the work.
70
I'm sucking on the straw.
71
I'm pulling the liquid up with my lungs.
72
At this point I want to go off on a bit of a tangent
73
and talk about a type of pedantry that I think isn't always helpful.
74
Like imagine you say I'm sucking liquid up a straw now.
75
I mean it's a weird thing to say out loud
76
but hypothetically and then an annoying physicist comes along and says well technically you're not sucking water up a straw,
77
it's the atmosphere pushing it up the straw.
78
And then in the next breath
79
that physicist might go on to talk about the flow of positively charged holes in a semiconductor.
80
Well, holes don't flow and a hole can't have a charge.
81
So why is it okay to talk about the flow of positively charged holes?
82
Well, the reason it's okay is because it's useful.
83
But I would also argue that it's useful to talk about a suction force.
84
So long as you keep the underlying physics in mind, you should be okay.
85
Like, for example, you can't just increase a suction force indefinitely.
86
Eventually, when you get to about 100 kilopascals, it stops working because you've run out of atmospheric pressure, the thing that's really doing the work underneath.
87
Similarly, I think it should be all right to talk about the flow of cold.
88
Like if I put an ice cube in my drink, the cold flows from the ice cube into the drink.
89
Of course, that's not really what's happening the warmth from the drink is flowing into the ice cube
90
and so it gets colder.
91
But it's useful to talk about the flow of cold, again, so long as you understand the underlying physics.
92
Like, you can't just keep pumping cold into something because eventually you reach absolute zero.
93
By the way, these animations are from a video I made about how all LEDs are secretly solar panels
94
and all solar panels are secretly LEDs.
95
The link's in the card and in description.
96
Okay, tangent over.
97
The point is, we all know that for the water to get out, air needs to be able to get in.
98
And with your finger off the hole, well, air can get in at the top.
99
But if you cover over the hole, the only way for the air to get in is through the spout.
100
And that's where surface tension comes in.
101
Surface tension acts to minimize surface area.
102
You might think, well, Well, one way for the water to get out is if the air can sneak past it on the way.
103
But what would that look like?
104
Well, it might look a bit like this.
105
You've got a drip of water starting on one side and on the other side, you've got a bubble of air forming.
106
But see how that increases the surface area of the water.
107
And because surface tension acts to decrease the surface area, that's not energetically favourable and so you don't get this bubbling effect.
108
And instead the liquid is trapped inside the chamber.
109
This is also the principle behind a magic trick by the way sometimes called inexhaustible bottle or thinker drink.
110
It's usually a bit more elaborate it'll have more chambers
111
and different options for drinks but anyway you can read all about it in my kids book
112
Science is Magic available from all good bookstores.
113
So these are magnets yeah and then these are metal
114
so they stick to the magnets and then when they drive around they also go around with it.
115
And that makes it spin.
116
Yeah.
117
And some of them go loop the loop like this.
118
That was my daughter spontaneously explaining the mechanics of the thing that she just built.
119
The thing she just built was from a KiwiCo project, the sponsor of this video.
120
Actually my kids have had a KiwiCo subscription since way before they approached me for sponsorship
121
so I can tell you a bit about them.
122
It's a subscription service where a box comes in the post every month
123
and everything you need for the projects is in the box.
124
You never need to run off to the shops or anything like that.
125
And the projects are STEM projects.
126
There's eight different subscription lines for every possible age group.
127
You know, something that I haven't talked about before
128
that I really appreciate about KiwiCo is the spontaneous STEM discussions that arise from it.
129
You know, I'm the sort of person who, like a fact will pop into my mind and I'll say,
130
hey kids, did you know this thing about the moon?
131
You know, whatever.
132
And, you know, it's completely out of context and the kids are sort of like, well, okay, fine.
133
You know, so these days I'm on the lookout for, you know, STEM discussions that are within the context of what we're doing.
134
And KiwiCo is great for that because the kids are so invested in the projects already.
135
Like they're building these things, they're excited about them.
136
And then as you saw with the explanation, these STEM discussions arise spontaneously.
137
And it's really amazing to see.
138
We've got a promo for the holiday season.
139
Perhaps you know someone who would appreciate a KiwiCo subscription, in which case you can get the first month absolutely free using my special URL
140
if you go to kiwico .com forward slash Steve Mould the link is also in the description so check out KiwiCo today.
141
I hope you enjoyed this video if you did don't forget to hit subscribe
142
and the algorithm thinks you'll enjoy this video next.
143
When I touch it like that, it spins.
144
So do you think the air is doing the same thing?
145
Yeah.
146
You're saying that the air from the candle, the candles making the air push up on those red things.
147
Yeah.
148
Oh, I see.

מהי טכניקת השאדואינג?
שאדואינג היא טכניקת למידת שפה מבוססת מדע שפותחה במקור להכשרת מתורגמנים מקצועיים ופופולרית על ידי הפוליגלוט ד"ר אלכסנדר ארגואלס. השיטה פשוטה אך עוצמתית: אתה מקשיב לאודיו באנגלית ילידית וחוזר עליו בקול רם מיד — כמו צל העוקב אחרי הדובר עם עיכוב של 1–2 שניות בלבד. בניגוד להאזנה פסיבית או תרגילי דקדוק, שאדואינג מכריח את המוח והשרירים בפה לעבד ולשחזר דפוסי דיבור אמיתיים בו זמנית. מחקרים מראים שזה משפר משמעותית את דיוק ההגייה, האינטונציה, הקצב, הדיבור המחובר, הבנת השמיעה ושטף הדיבור — מה שהופך אותו לאחת השיטות היעילות ביותר להכנה לIELTS Speaking ולתקשורת באנגלית בעולם האמיתי.
