SPOILER: It doesn't explode :(
This is a video from Syracuse University of some homemade lava with a temperature of around 1371°C (~2500°F) being poured over a six-foot slab of ice. Personally, I think it looks like a cheese pizza but that's just me and I haven't had anything to eat today except a breakfast bar. So yeah, lava on ice. Pretty neat, Syracuse, but I've seen Disney on Ice so it's gonna be hard to top that.
Hit the jump for the video.
