He Pours Molten Aluminum Into A Fish Tank. What Happens Next Is The Coolest Thing On The Internet!
I would never recommend doing something like this in your back yard if you don’t know what you’re doing but what came out of that fish tank after this guy poured molten metal in it was SO FREAKING COOL.
YouTuber known as the Backyard Scientist threw a whole bunch of these weird looking polymer balls into his tank and melted some aluminum cans in his homemade foundry (we’ve got tutorial on how to make those too). As he started pouring the metal I was afraid he’d be showered in broken glass but after the aluminum cooled down it turned into the most amazing sculpture.
