Last week Room 2 did an experiment called the balloon experiment  which was an experiment in which we used a balloon and a stick.  First we blew the balloon, not too big to just around 4 centimetres.  When I put the stick through the bottom left hand side of the balloon and the stick up onto the top  left hand side of  the balloon, the balloon didn’t pop. It didn’t pop because where I put the stick in to the balloon was the unstretched side.  That is why the balloon didn’t pop.
