  • That's amazing!

    Is that fluid you're working with in anyway toxic?

    How do you clean it up afterwards?

  • @karkovice10 You wouldn't want to eat it, but it's not toxic like, say, mercury. Soap and water generally suffice for cleanup, but if you get it on anything absorbant (clothing, wood, etc.) it's *never* coming out. It even takes a while to come off your skin.
