Well yeah, it'll spatter because the water explodes into steam. Sending molted iron everywhere. And steam. Not good.

uh yeah.. that's what i said, it gets the oxygen from itself, not from the outside. Which is why you cant smother it, like one could for a 'normal' fire drawing oxygen from the air.

Accidents can happen from something as simple as a drop of water very close to the resction, the reaction comes into contact with the drop of water and spatters all over the onlookers, not fun (and before you tell me that wouldn't work, my high school chemistry teacher saw it happen with just a few drops of water).

life is full of risks
FROM THE ALLMIGHTY WIKI! (the most convient source i could find at this hour)
"Thermite contains its own supply of oxygen and does not require any external source of air. Consequently, it cannot be smothered and may ignite in any environment, given sufficient initial heat. It will burn well while wet and cannot be extinguished with water. Small amounts of water will boil before reaching the reaction. If thermite is ignited underwater, the molten iron produced will extract oxygen from water and generate hydrogen gas in a single-replacement reaction. This gas may, in turn, burn by combining with oxygen in the air"
I don't see why you COULDN'T ignite it underwater. I just would highly recommend against attempting that.
