Aluminum can experiment
I am trying to complete an experiment to make an aluminum can move when placed on the floor. I cannot use anything on the outside of the can. Any suggestions?
Sounds like a question your teacher has asked you! Is this for homework or a science fair project?
Do you have any ideas so far? What are the other constraints? Judging by what you've told me here, you must try to work some magic with the inside of the can? Or is the can full and sealed?
If this is simply a brainteaser, why don't you do some thinking first (and maybe some web research).

It is for extra credit. The constraints are, the top is cut off the can and you cannot have anything touching the outside. I have tried attaching clay to the inside center. (It rolled, but did not continue to roll.) I tried to use taut rubber bands and a battery. (No luck.) I've also researched on the web and found nothing. (Well, I actually found this web site.) I'm drawing blanks.

A cam is a rotating disk shaped to convert circular into linear motion, while a gyroscope is something different. Look at: http://science.howstuffworks.com/gyroscope.htm
Also, is there a limit on NOT using battery powered devices? Or does the can need to move for at least a certain period of time?
