Alka-Seltzer added to spherical water drop in microgravity

Saturday Morning Science:
Alka-Seltzer added to spherical water drop in microgravity onboard the International Space Station.

(March 22, 2003) --- 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.

Astronauts have way too much fun! Similarly, I'd LOVE to see Mentos and Diet Coke in zero-G!

Isnt it like how a star behaves?

I learned that adding an effervescent tablet into a floating water will create an eyeball.

Stars don't have surface tension. That's why there's solar wind, for example.

[bobrulerofall]

no. if you had spelled sun right then maybe.

[Albert Villarreal]

do you think that this experiment has a similar reaction to the suns as it gives off solar flares

[kvpena]

This reminds me of what happens to gremlins when they get wet.

It looks like Jupiter.

[Honchobuns]

So does that mean that planets are hollow? They are at zero gravity with chemical reactions in the middle.

bubbles...

The water sphere is sitting in/on a wire hoop so that it wouldn't just float around the room
