My dad showed me a trick where if you stick a pin into a balloon at the top it doesn't pop.  So I tried sticking a pin into balloons at different places to see if there were different places it wouldn't pop.  It doesn't pop if you stick it in near where it is tied also. But we don't know why.  Please help us.
