Re: Physics of Toys in Space



Although the subject line implies zero g, Scott, my message had solely to do with a friction-free environment. Cliff Parker combined the two subjects in his message. None of my examples would be difficult in zero g as long as there was friction. I assume your open door has friction-free hinges.

A fun earth bound demo for simulating how difficult writing would be in zero gee is to tape a piece of paper to an open door and have a student try to write on the door with a hard lead pencil.
