Bro didn’t have to pull out the 6 dollar science toaster on us, but I understand. Had to flex on us a bit

7:31 Did you notice your sphere also GREW as it got hotter? (very obvious in this back-and-forth clip) A very metal like quality heh Which people leverage to do things like getting two pieces of metal apart, heating the outer metal. Same if needing to put them together. _(or by doing the opposite, putting one in the freezer)_ _edit: __9:23__ ha... Albeit rather different, and yet equally curious!_ _edit 2: ~__24:30__ Hey hey, now he noticed!_ 😅

very intersting, you could try making a salt glaze for your clay-thermite! The sodium reduces the melting point of the clay locally, creating a glaze. This has also been done historically with normal clay firing

The pipe would have a different coefficient of friction. The wheel and the air apply force in different ways. The amount of force would have to scale properly... interesting experiment, lost of variables to play with!

sending this video to my mom

The squiggles remind me of that chain fountain phenomenon that swept RUclips a couple years ago. Chains, strings, springs, all have really counterintuitive physics when they fall.

Got to say, this is really high quality content for such a small channel!

Aluminum oxide is a really good abrasive and therefore pretty hard it's also Sapphire, so you might be making crappy Sapphire clay which is saying something it's probably mostly trash Sapphire but in that shape it is super easy to make and reasonably effective at being hard which is why it skates a pin, it's terrible shitty Sapphire, which in small granular form is like ceramic. I should really like to see a large sheet about 3x8 in and see if you can make a sharpening stone a sapphire sharpening stone could be a million dollar idea

I would love too see a video explaining the science of this.

Awesome idea and great prototype to start with

I thought Ricky Berwick got into science videos from the thumbnail haha.

phenomenal experiment!

This is nice, I'd like to make a few cones and burn them from the wide side to see at what thickness they stop burning

This is awesome.

Hey, neat

Very interesting video. I think most clays are not pH neutral; Kaolin a little acidic, maybe that's causing the adverse reactions.

9:53 What was the pH of the material? Aluminum oxide is amphoteric dissolving in both strongly acidic and basic solutions! If the clay contained carbonates or hydroxides, the dehydration process could've become too alkaline and dissolved away the oxide layer.

i could see the clay particles mechanically abrading the oxide layer on the aluminum powder when the two are being mixed, allowing the reaction with water to happen much more quickly

nice, and Al2O3 is a strong ceramic. did you try with SiO2 plaster as the clay. yep SiO2 is castable as slurry. aluminium oxide with impurities is a gem stone. you will have pure metal inside the fired ceramic tho. usually adding water to oxides makes them generate hydroxides and heat, that would accelerate hydrogen generation of the aluminium with water. instead of trying to fire the clay, how about adding iron powder and putting it in the microwave. also you could try mixing graphite in the clay and microwave that.

Would dipping wet clay in thermite to make a layer do the job?

You could try to insulate the clay when it is firing. Love how you test this!!

As a side note, the kaolin and aluminum could be used to make MRE heaters. Seems to put off considerable heat.

A touch of sulfur or magnesium powder would make it easier to ignite.

The pattern of burning looks a lot like the slow motion shots of thermite in veritasiums latest video

This was absolutely wicked! I cannot wait to see what you're able to do next with this, is seems really neat, and possibly incredibly useful!

This is really smart, I recently bought some plaster for castable thermite but this is even cooler.

Great video let’s see a basketball size ball of clay and aluminum ignite

*ClayMite™* (not really ™ so feel free to use that lol)

This is fascinating!

The cylindrical object being levitated is because the airflow is around or all around the object evenly, creating lift. Hold the nozzle back and from below to begin with.

Its to heavy its dragging on that bar

Imagine being this guys neighbor 😂

How the hell did you never try to blow under the rod and not on top of it? That's more logical in terms of forces, that's how people make objects floating in the air like you tries with the tape, AND that's closer than what happened with your bracelet 😅 Try that, also with different angles

Drop it into a big teflon pot. Some kind of low-friction surface at the right angle... plumbers tape wrapped around your board?

That bracelet is the answer to the question of "what do I do with all this arm hair?"

The chain is giving Saddam husain hidding spot

Lets talk about the bracelet for a minute.... Are you selling them? Where can I get one?

this man is a true scientist

Make the chain without the master link it's an imbalance making it harder to spin up.

heres a bad idea u shud fling it into a neighbours open window whilst its spinning.

Damn, you got alot of water in your tank.

Great investigation, thanks for being curious and just a little obsessive...

I want to know how you made the bracelet.

I feel like each of the edges of the chain links slapping the small diameter pupe is inducing certain frequencies into the chain and causing drag, which leads to "wiggly" effects on larger length chains. It's harder to end up with bends in the small chain and easier to overpower with less air.

try a wheel bearng 🤣

Looks like a topic for Steve Mould :)

Water would be more effective then air

Ruined a whole day.

Nah just use a turbine, it's much simpler.

0:59 the squiggly pattern😮 It's the @SteveMould effect! He should definitely see this.
