Alka-Seltzer in Space.

What do you get when you add Alka-Seltzer to a spherical water drop in microgravity?

Expedition Six NASA ISS Science Officer Don Pettit performs a series of microgravity experiments with water spheres and effervescent antacid tablets. In the second of four videos, Pettit inserts a tablet into a 50-millimeter sphere and observes the fizzy results.

    And this is what we pay taxes for…. Billions of dollars spent on the Space program so some Astronauts can play with alkaseltzer…. I want my money back

    I don’t mind my money spent on that at all. In fact, I liked it so much, I’ll refund CK’s share of the experiment.

    P.S., CK: Personally, I think this is a much better investment than the war in Iraq…

    Jenny, Agreed. But I can think of a dozen better things to spend a million or two on. Am I wrong?
