The Backyard Scientist Pours Molten Aluminum Into a Tank of Water Beads to Create Unique Metal Designs

The latest experiment by The Backyard Scientist involved pouring molten aluminum into a fish tank full of water beads to see what kind of interesting designs were created as the molten metal flows down.

I packed a fishtank completely full of water balls (water beads, water balz, spitballs…). Im guessing there are over 10,000 in there! Anyway, I melted a bunch of old aluminum pipes and poured them into the fishtank hoping to create a cool design. And it worked perfectly! These are really unique, no two pieces are alike.
