I built a bed of nails that supports a balloon with a brick on top of it 
for a 6th grade science fair project.  I understand how this works (pounds 
per square inch is reduced to the point where the balloon is not pierce by 
the nail).  I have been trying to find other things that work on the same 
principle.  I have found much.  Can you help?
