need to make everyone think you have super strength ? Or perchance you want to do a short film where it looks like the fabric of reality is breaking down ? All you need is some aluminum , some gallium , and some patience .
If you want it to look like you ’re hulking out in front of your friends , or have weird powers over affair ( or at least metal ) , it wo n’t cost you more than twenty dollars to do it . There ’s a really cheap particular impression that you could do , and ask a little element called atomic number 31 . Gallium is a metallic element that ’s notable for melting at around room temperature . It ’s seldom found on its own in nature , but you may find unadulterated gallium online . It will only run you about twenty bucks for fifteen grams of the stuff .
Gallium is n’t dangerous to humans . Plenty of people order it in society to play with it a little , permit it meld in their hand , then rain cats and dogs it back into its container and let it re - solidify . As long as you do n’t eat it , it ’s not dangerous .
Perhaps a better manner to phrase that is , it ’s not toxic . It can be quite dangerous if you were to spill it on a plane , or a bike , or any other atomic number 13 structure that you desire would furnish you ( or anyone else ) with structural backup . Gallium , when invest on aluminum , will tardily diffuse into it . As gallium spread through the aluminium , it lends the Al some of its plasticity . Give gallium enough metre to move through an aluminum complex body part , and you’re able to tear into the aluminum with your bare hands .
For large structures , you ’ll involve more gallium than fifteen gramme , but fifteen grams is a good starting signal for a merriment effect . Put atomic number 31 on an empty tonic can . Scratch the can a bit with a coin or a knife just before the gallium is on it . ( Aluminum would be a very reactive metal if , in an oxygen - racy environment , it did n’t report itself with a layer of nonreactive oxide very quickly . come up the can will step on it the Ga ’s submission into the aluminum . ) Leave it for a few hours or even a few days . The bead of gallium will slowly disappear as the atomic number 31 molecule move into the can to create a soft alloy . When you come back , you should be able to drive a fingerbreadth through the sides of the can with almost no travail .
The same matter take place with larger objects . Enough Ga added to an aluminium bicycle or any other musical composition of aluminum will make it relatively easy to shoot the metal aside . So get some gallium and a television camera , and impress your friends .
