A simple solution to a common problem!
Cool indeed, but very strange looking, too! How did the (wet?) beads react to the molten metal? I'd 'a thunk there would have been a fantastic steam eruption, or that the most of beads would have floated to the surface. Lots of odd things going on there. Now to find a use/customer for your very artistic sculptures ...i got a 2 lb bag of water beads to add to a 35gal. drum with water as required to make them swell up to about 1/2" diameter. melted up a few crucibles of aluminum and did a couple of "pours" into the solution. very interesting results. then i melted some brass and did the same thing, into the tub of these little balls. again, interesting results. here's some of what i ended up with. . . cool, eh ?
