Alka-Seltzer in space...

This was interesting to watch, as the water and Alka-Seltzer react. It was not really the result I expected either and as one of the presenters says, "That is why you run experiments", to bridge the gap from the theoretical (what you think will happen) to actual (what does happen).

I would be curios to see if no having the wire anchor changes the results any. Does that contact point have an effect on bubble formation and migration.

Give it a look see, it won't hurt a bit!
