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.

@obrian93 More like $0.05 (the cost of one Alka-Seltzer tablet)—excluding the cost of water—well spent, since this was just to pass time. Unlike what some people think, these little experiments were not their purpose of going to space. Imagine spending months, if not years, in space without doing things like this to pass time, but only eating, drinking, and sleeping. You would probably go crazy! Plus, it adds to their knowledge, which could benefit them in the future somehow.

@kirkneddy I have I have completed them ranked high in my classes. and that's why I know it doesn't just cost 5cents to perform this experiment. I challenge you to replicate this under 100 dollars:)

[ryanmerkle5]

@EnterARandomNameHere $22,000 per KG for a space mission is good. So wasting weight can be terrible. Lol you have obviously never taken a physics class.

[EnterARandomNameHere]

@ryanmerkle5 Because I didn't get a job going into space, therefore I can't do this experiment. You make it seem like they went into space solely for this. I can never understand why people troll. . . .

[KirkNeddy]

@ryanmerkle5 I see you've been trolling this video for a while now. Take a physics or chemistry class sometime so you can complain how universities use their millions of dollars gained in tuition to have students perform mundane experiments with just water. There's plenty out there for you to hate, don't stop here!

[ryanmerkle5]

@EnterARandomNameHere They spent energy, time and film doing this. You cannot nullify the cost of actually doing the experiment. You are saying that doing this experiment cost a mere 4 cents, so why don't you do it on your own and tell me how much you spend.

[EnterARandomNameHere]

@ryanmerkle5 But the cost of those items is only included if the PURPOSE for them was to enable the astronauts to do this. That's far from their purpose, therefore they wouldn't be included in the cost.

thats how god did it with a giant alka-seltzer

[jimboli12345]

multiplying bacteria?

[ryanmerkle5]

@EnterARandomNameHere what about the money spent on shipping both the alka-seltzer and water up to space? including the food that was used to provide the astronaut with energy used during this film. oh and how about the energy to record this... not just 5 cents... but thats just my 2 cents.

honestly, how cool is this!?
