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?
