What was the science experiment at school...

[Diamondback]

Where you drop something in water, and it bursts into flame and whizzes across the surface? I suppose what I really mean is, what was the substance?

Help me MN Geeks, you're my only hope!

sodium

Sodium I think

Flame Boy?

I dimly remember this from a chemical reaction vs physical reaction lesson. Google it, go on, I dare you.

Lithium is more dramatice

Hurrah! I'm going with Lithium - mmm, flamey

Thanks ladies!

PS, I found this while searching on YouTube for Sodium in Water

"I was at the mall and I saw this, and the first thing that popped into my head was 'I wonder what would happen if we were to put this in liquid nitrogen?'"
