during the ball chain, i love how adam looks like a big baby with that smile XD

[@KandiKlover]

He's cute :3

14:30 excuse me, Adam has done what? 💀

[@sumitrokaya7597]

I love how they teach us science in practical and fun way👍😁

[@TheCardinalFang]

The ball chain thing is also known as the "Mould effect", named after it's discovered Steve Mould, who has his own science channel on KZbin. He also appears as one third of the Festival of the Spoken Nerd, another member of which is Matt Parker who runs the Stand-Up Maths and Numberphile channels and who occasionally appears on Adam S's Tested channel doing something incredibly geeky with maths

[@neiltarrant7253]

I think Steve wouldn’t claim to be the discoverer of the ‘Mould Effect’, but certainly popularised it - his video on the subject I believe was released after this episode would have aired.

[@TheCardinalFang]

@@neiltarrant7253 Steve Mould's KZbin video about the chain fountain came out in 2013. The Mythbusters episode about it came out in 2014

You can get a motorized toy with a loop of chain to take this even further.

[@dominikmuller4477]

steve mould figured out what drives the ball chain, if you're curious

For anyone confused like I was, this was actually episode 5 of season 12.

Also they make a motorized toy with a continuous loop to do that ballchain trick as long as you want and also let's you shape it.

I often found when growing indoors in a sealed environment like this the middle plants grow best. I think it's to do with being near the centre of the lamp. Every couple of weeks I used to swap my pots around in the room rotating the outside to the middle and then they all grow equally.

[@thorpizzle]

Except for the plants with no water.

[@michaelmayhem350]

I can't believe they didn't teach us how to build a nuclear reactor. Someone has already built one at home before.

[@creato938]

And irradiated half the neighborhood on the process, i am well aware of that story.

[@michaelmayhem350]

@@creato938 pretty sure it was more than half 😂🤣

[@LENZ5369]

If you are talking about that boy scout guy; then no -he pretty much just gathered a bunch of radioactive material in one spot. Calling it a 'nuclear reactor' is like putting a little gasoline in a jerrycan and calling it an engine.

[@ztyy8185]

I believe the metronome may not have worked because they were floating. They could move in all direction's instead of just moving from side to side. When Adam moved them that way they did sync....

[@Goalsplus]

Yeah, they changed the suspension method.

[@KandiKlover]

@@Goalsplus and probably too light of board to set them on. But that's why we're allowed to try at it home.

[@Goalsplus]

@KandiKlover that made me laugh. The idea that we shouldn't try it at home because we would make it work when they couldn't!

[@Gowerrr]

There is too much MASS of how many metronomes there are for simple air to overpower the friction. They should have just done a simple cylinder and plank setup like Adam proved worked. Even when Adam simulated to lateral oscillation on the air table it worked like it should in the regular experiment. He should have noticed there was no table moving, which he learned was pivotal to the premise.

Any chain or rope can "levitate" like this but in the right conditions.

[@MrKfadrat]

middle plants grow best because they get most light, almost half more than the side ones with no reflective walls

[@mirawenya]

That boat stunt looks dangerous as hell...

[@Sethioz]

that ball chain thing reminds me of something else that i noticed that shouldn't be possible. when you take one of those dish washing sponges, or well not really a sponge, kind of cloth, but with rough texture. it's the part on sponge that is attached on one side. that kind of thing. put it over edge of any container, so it's hanging about 70/30 (inside / outside) and then fill it with water, water will climb thru the cloth and go over the edge. this continues til water is below the level where it touches the cloth. it's kind of like siphoning fuel or any other liquid, but what i don't get, is how this can work in sponge / cloth? reason why siphoning works, is because of pressure, but that cloth is not air tight and you don't need to make it start manually, it goes on its own, water literally climbs up the sponge and out on other side. and i mean open container. i first noticed this when i left bowl in sink and that cloth / sponge hanging over the edge, i later noticed that lot of water was missing from bowl. i tested it and it works every time. i guess that spongy texture is able to trap "pressure" and similar physics to siphoning is happening on microscoping levels. would be cool if someone made a more proper test on it and show how/why its happening.

[@snarzetax]

A few years ago, people walking on a bridge proved Adam's observation of synchronism was right, after all.

[@KandiKlover]

Oh there's been numerous occasions of that the past 100 years. There's been suspension bridges closed because of it.

[@SirZechs77]

Imagine getting a guest appearance from NileRed on the chemistry bits

[@alipritchard7193]

surely a fire on a boat like that would be engine related, with some sort of combustible fuel involved? I doubt the boat was on fire because someone threw a pallet and some straw on it?..

[@Loljdk]

The secret compound is amino nitroaniline

[@Damien321]

Amazing 🤩

[@Henipah]

Microwaving water can be really dangerous if it becomes superheated.

[@marystar1924]

The metronomes would have probably had a bigger chance if they shared the same surface as showed earlier on the show. A cushion of air is not a shared surface.

[@nathanellis3111]

That would be straw, not hay.

[@burningatthetrailhead]

True. Straw is the stalk. Hey is for horses 😂 not sure they feed horses the leaf and molasses anymore but they did way back in the day.

[@nathanellis3111]

@burningatthetrailhead I have to disagree. Here hay is different than straw. Hay is for eating, straw is for bedding. Straw and Hay are different.

[@Valfaun]

damn, i don't have a lake, a speedboat and a second boat that's also on fire at home

[@BabyMakR]

The reason the metronomes didn't work is because the panel moves in 3 dimensions. If it could only move in one, like the first one with the rollers that moved left to right, it would have worked.

[@burningatthetrailhead]

It bothers me they didn't use DI/RO water, tap that's PH to the correct range and di/ro that has a small amount of plant food that's also in range for the microwave experiment

[@renakunisaki]

I can think of some reasoning why microwaved water might be "worse" for plants. If you're boiling water for plants, you're probably under a boil water advisory, and need to remove contaminants. If you boil it on the stove, the contaminants can easily escape in the steam. In the microwave, they're more constrained, and you probably have a lid on it. So the microwaved water won't be cleaned as effectively as the stove-boiled water, and might still contain toxins. I'm sure the myth just comes from people not understanding what radiation is, but, that factor might compound it. The bigger concern with microwaving water is that it can become superheated and "explode" when disturbed. Be careful!

[@danielmadar9938]

😂❤😂❤

[@Ma_X64]

Well, if microwaved water gave taller plant then there IS a difference! It would be interesting to investigate! I, personally, think that the point is in the water molecules clusters: microwaves destroy them lowering viscosity or/and surface tension, so the plant can suck it in easier.

[@568dodo]

its probably due to relative positioning to light source and probably a lot of other factors.

[@Ma_X64]

[@lubin015]

That's just what happens when you remove oxidizer and put something with higher thermal capacity into fire

[@AkiSan0]

@@lubin015 those are a) two different sides of the triangle and b) not whats happens with water spray. maybe i misunderstood what you meant edit: technically even more wrong as thermal capacitiy, thermal conductivity and thermal level are three different things. capacity is how much it holds, conductivity is how fast it can exchange (think of heat shielding or aluminium foil) and the third one is just if you throw in cold water vs hot water. ;)

[@Games_and_Music]

Ahh good, thanks for the clarification, because when he said that i literally thought out loud: "Really? Is that what happens?" I am no scholar on any of those things, but it did strike me as odd, as i tried to visualize his explanation and it didn't make a lot of sense. But i did remember my sister telling me recently that water doesn't have a lot of effect on really high temperature fires, so i was starting to think that the main effect of throwing water on a fire was because of taking the oxygen away.

[@lubin015]

@@AkiSan0 the lack of heat is just side effect of not having oxidizer
