No Pop Balloon
When you puncture the balloon, it is not air rushing out of the hole that causes it to pop. Itís actually called catastrophic crack propagation. This means that it is the eventual spreading of the hole that causes the balloon to pop. The hole spreads, in effect ripping open the balloon. The tape slows down the process so that it can be seen more clearly.
1. Would this experiment work without the tape?
2. Would this work if there was no tape but the pin was lubricated?
3. Does it matter if the balloon is inflated more or less?
