Mirror-Polished Japanese Foil Ball Challenge Crushed in a Hydraulic Press-What's Inside?

Published on Apr 10, 2018
In this video I make a Japanese polished foil ball by using aluminum foil and pounding with a hammer and then polishing until it becomes a solid metal polished ball! These polished foil balls started with a Japanese jeweler who made one that appeared to have no purpose, but the nation became obsessed with it and everyone started making them! You can see what's inside an aluminum foil ball when I crush it in my hydraulic press and see if the density increases or not.

  • what did you expect ?

  • 4:30 you thought all the work for nothing

  • Can you make one of these balls using a hydraulic press? Get it closer to the density of real aluminum?


  • Now I know how to find out the dencity yay

  • Now I know how to find out the dencity yay

  • İt is a shame that u pressed a perfect ball oh man if i would have it i would never press it

  • Who wanked?

  • using sandpaper on aluminium foil, good way to get alzheimer

  • I came across this article "What would happen if oxygen disappeared for five seconds?" www.independent.co.uk/news/science/what-would-happen-if-oxygen-disappeared-for-five-seconds-8925756.html In the article, it says "Oxygen is an important binder in concrete structures (really, the CO2 is), and without it the compounds do not hold their rigidity." So if a concrete block is placed in a vacuum chamber, would it really turn into dust?

  • Um... how can aluminum be "lighter than aluminum already"? And how can you say it's about "half as dense as 'real aluminum' " when that IS real aluminum? Plus, why didn't you write your comparison as "Japanese aluminum ball" vs. "SOLID aluminum," so as not to make it sound like this ball was somehow made up of... "um... something that isn't aluminum..."?

  • Mmmnghh... not quite as good as those other people did, but still better than I'd likely have the patience for!

  • Man you are really cool.

  • Wow. You made a ball using aluminium foil!!!

  • Will Americans ever pronounce aluminium right?

  • Get on with it

  • Guys subscribe to the channel

  • Please do what if you do a mirror polished foil ball in a vacuum chamber

  • just under a third of the density is *not* "Just less than half"

  • うわ〜!!キレイだな〜〜🤩🤩🤩🤩

  • Are you sure you will make are dream come true

  • do this again but instead of the ball challenge your end goal should be creating a black hole (actual black hole)

  • You didn't even finish the ball!

  • You should have weighted it before starting to make the Ball to establish the weight loss during the process of compacting it!!

  • u didn't told us about its weight

  • 4:00 Why does thst sound like ky school?


  • 1:46 Did anyone notice something?

  • Lo d

  • All his efforts "flattened"

  • I want my head crushed in that press.

  • For some reason I badly want to stick it in a microwave.

  • Nerd alert

  • Aluminium not aluminum

  • can u use 2 electro magnate where they placed 1 inside another ----> [ {} ] this 1st electro magnate----> { this magnatic flux shuld be x3 den outer electro magnate 2nd electro magnate----> [ both shuld be opposide to to eachother those shuld act like pulling and pushing force my point will it create new kind of magnaticr field which has N&S pole feild around it it may creat new kind of force

  • Dude your vids are cool to watch but your voice makes me want to rip my ears off.

  • New age Professor Proton 🤓😁

  • Why sand when it’s foil? I thought it’d flake. Meh, it worked.

  • How to make a solid ball of aluminum: 1. Well, aluminum is a solid so... 2. Just crumble up a sheet of aluminum. 3. Ur done dude

  • Real smart pounding on your granite counter tops..... ;-)

  • Aww, you should have tried to crush it onto a neat little cube!

  • Aluminium, not Alu Min Um. Americans!

  • velely guld

  • worth your views

  • hitting 20M views :0

  • Is it me you're r does he sound like pewds

  • Can you make like a silver bar look

  • we all da big NERRDSSSSSSS

  • Nerd. □~□ O

  • Your so awesome!!! I subbed!

  • HI Try dropping a feather and a coin in vacuum chamber and normal atmospheric preasure

  • This guy sounds like Chad alan

  • this idiot got dry sandpaper wet, then used wet sandpaper dry

    • Yeah he is an idiot he is basicality science geniua thats idiot

  • Make a black hole.

  • So SHIT!!!

  • This look like a moon(sorry i know english bad beacause im from Rusia)

  • Inside I think there would be some aluminium foil. No shit sherlock

  • 0.85/2.7 is not half as dense but just 31.5 % as dense.

  • Fake

  • What wood happen if there was no light in the world. (Or if the world was only water) '_'

  • Hah brave guy to do that on his counter top

  • 0:42 the action lab : it wont work if i do it that way it will take forever i will use my super powers and it is SUPER SPEED HAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

  • Remember your first vid is you crushing a golf ball , wow that was 2 years ago dang

  • Fruit in a vacuum chamber, will it decompose? Or lose it's structure and explode?

  • Silver pancake anyone

  • *I really do wanna know what's inside an aluminum foil boil*

  • The gross hairy arms were too distracting.

  • Put one in your vacuum chamber

  • Ok.... So its a ball right??? Ball=Sphere...Why did u use water displacement method it is not irregular.....

  • What's inside aluminumball? air duhhhh.. Its a ball

  • The biggest question... Is thid how air planes r made? XD lolll

  • An American (USA to be specific) that uses the metric system! Thank you! -rest of the world

    • OK, good, Sai. Oh, I see that you edited it. Good! I once helped shoot a sociology telecourse where the teacher called us (people from the USA, like me) US-Americans, rather than just "Americans." So that might even be a better edit (and then we could delete our following replies, like this one right here).

    • +Maxx Fordham! oh sorry I mean the United States of America

    • Um... a LOT of Americans had already been using the metric system for a long time. Think of Brasil, Chile, Canada, Mexico, Argentina, Colombia, etc.

  • put it in two buns and eat it!

  • Crush it again and again and again again again..... until you have a tiny solid ball. :D

  • Your boring

  • Did japanese people actually start this? Because it seems like those things Americans call Chinese or Japanese but they're from America

  • Aluminum lighter than Aluminum

  • That was a rain gauge thing

  • From a jawbreaker to a pancake.

  • Why didnt you cut it with 1000 degree knife

  • Hi

  • How did this trend start?

  • looser

  • What happens if you put ice in liquid nitrogen?

  • Can you make an action lab about proving that Earth is Flat or Globe? Cause so many people talking and argument about that.. Just some stupid ideas from me, thanks

  • You should vacuum water

  • .7 cms *thicc*

  • > alumiNUM E-esh... It sounds so stupid.

  • do a cube tinfoil

  • Benjamin Rivera it is made

  • "First, let's get my ball" Hey, impressive ball you got there.

  • Please give new video of spinner

  • Wow amazing work

  • Stick gallium in the foil ball.

  • The original creator of the aluminum foil ball never sanded the ball to get it shine. He only hammered it to get shine.

  • 3 2 1 Drum roll Squashed Thats what the sound sounds like to me.😂😂😂

  • Someone tell the terminator from judgment day, action lab crushed on of his balls 😅

  • I thought the water at 1:31 was fire 🔥 lol

  • U can put in the microwave 😏😏
