What is it like in space?

Space is a very cold habitat. We must wear special protection to avoid harm. How cold IS it?
The instructor immerses a straw into a container of liquid Nitrogen to demonstrate the effects of cold in space.		Later the instructor places a balloon filled with air into the same container. This illustrates the difference in the amount of storage required for liquids vs. gases as rocket fuels.
When the instructor removes the straw into the very cold Nitrogen and attempts to bend it...SNAP! The portion of the straw that was immersed breaks off with a sharp snapping sound. That portion of the straw is no longer flexible as it had been. Sure glad that wasn't a human arm or leg!
		The instructor places a marshmallow into a special container that is used to demonstrate the effects of the vacuum of space on humans.
Space is a vacuum. What kind of pressures would that exert upon objects in space? Believe me, you would not want to be that marshmallow!
		Do you know what EMU stands for?
Astronauts wear special suits in space to protect them from the dangerous cold and pressures of space. Think of all the things scientists would need to consider when creating that suit.
