Physic- 16
Quite an interesting question asked by Mr Lim yesterday:

How do astraunauts pee/poop?

This are the steps to poop like an astranauts. *(laughs)*


Step #1: Get a baggie and some duct tape.
Step #2: Put the mouth of the baggie up against your anus.
Step #3: Tape the baggie in place with some duct tape. Make sure you get a REALLY
good seal!
Step #4: Poop. DO NOT PEE!! Peeing is covered in NASA Technology Transfer
Bulletin #A101-753A.
Step #5: When you are done pooping, CAREFULLY remove the baggie from your butt.
Step #6: Wipe. Wiping is covered in NASA Technology Transfer Bulletin #A101-
753C.
Step #7: CAREFULLY dispose of wiping material in baggie.
Step #8: Seal the baggie using the duct tape that held it to your butt.
Step #9: Dispose of the baggie in the nearest trash receptacle.


Not only that, you have to contend with Newton’s Third Law, which is: “For every action, there is an equal and opposite reaction”.
Simply put, this means if you let loose a big one without some kind of restraining mechanism, you’ll go flying right across the space
module, probably upsetting some important experiment involving how bugs reproduce in space.


You know what? I've read on wiki answers that astranauts drink their pee. GROSS! ): Well maybe it's not true. We still can bring water along into space right? One question, will the water float around if you just pour it into the space? If that's the case, I guess it must be really cool(:
Weightlessness is quite amazing after all.

Another set of answers:

Astronauts brush their teeth just like they do on Earth. There is no shower on the Shuttle, so astronauts must make do with sponge baths until they return home. Each Space Shuttle has a toilet that can be used by both men and women. Designed to be as much as possible like those on Earth, the units use flowing air instead of water to move waste through the system.
Solid wastes are compressed and stored onboard, and then removed after landing. Wastewater is vented to space, although future systems may recycle it. The air is filtered to remove odor and bacteria and then returned to the cabin.


That's it for this post(:
