Today in science we were discussing the reactions of a balloon, and what 
would occur if a hole was poked in the balloon with a pen and what would occur if the back of the balloon was cut off. As a result of testing this prac we have found out that stabbing a hole in a balloon with a pen would pop the balloon and a loud noise would be made, whereas cutting the back off the balloon would not end up in the balloon tearing and creating a loud noise, it ended up in just releasing the air fairly slowly.

This was a great discussion JT. The result was unexpected considering we are used to balloons popping when they are pierced. A great reflection!
