If you were to touch lava, unprotected, at what rate would the hand "melt" in contact? Just curious if the hand would "evaporate" when under the surface or just burn away slowly.

What you call "lava" is actually molten rock material, at surface its minimum temperature is around 800º C. I have no idea what happens with human flesh at this temperature, but I know nothing good would come out of this... :-)

I'm disappointed, I wanted to see the finished cooled off thing.

#5 it will catch on fire (even the parts above the surface) and get charred. You can see that even ice does not melt and evaporate quickly enough to create an explosion or even a violent reaction like hot oil and water.

Food for thought?
From the way it looks, I believe the bubbling is from the steam (from the ice) underneath the lava. Because lava viscosity increases while it is cooling, they can trap the superheated steams and form bubbles. It is quite amazing that the bubbles don't break immediately; probably have something to do with the elasticity of the cooling lava. Another thing to think about is how the ice melt. Could the lava have enough heat to change ice to steam directly? If so, the pressure should be quite high!!

PS: This really reminded me of glass making when the maker blew into the tube holding the heated glass to make different shapes. The lava should contain a lot of glass (silicon) in it.
