Ha! And them wacky 'scientists' said there ain't no water up thar on the Moon. Looks like them folks need to get themselves some learnin', cause here'd be the proof of it!
Canon 40D, 100mm macro, StopShot, and 2 x YongYuo flash units; one on the left with yellow gel, and one on the right with blue gel.
The image of the moon (which was placed as a background so as to reflect onto the water) was taken with a Sigma 80-400 with a 1.4x teleconverter.
Oh and yes, this is another water droplet collision shot
