More Falling Sand Sandbox
Ive discovered that you can do interesting things with Acid+Glass & the pause feature. What this is is a mixture of sand & partially perpetually molten glass due to particulates getting stuck inside the glass/sand as they fall after being melted in mid-air with the pause feature activated.... then letting the game resume & they fall together, forcing an unnatural mix. The ever-molten glass also causes the game to register constant heat, which makes the water boil.
The white/silver stuff inside the yellow mixture is glass that was able to cool inside the sand.
