How do you sleep in space?
Like a baby. That is, you sleep in a carefully wrapped mattress strapped to a wall. (However, you can sleep on the ceiling if you feel like it.) Astronauts also tuck their arms into a pouch to keep them from floating. No one wants his own weightless arm slapping him.
How do you go to the bathroom in space?
Space toilets don't have gravity to pull the waste down. Instead, they work more like a vacuum cleaner that sucks the waste into a container where it's dried and compressed to save space and avoid contamination.
Gee, I'd like a real space station. How much did the ISS cost?
About $13 billion so far. That's $13,000,000,000. Better start saving your allowance.
