Balloon kebabs anyone?

Last week we had a few kids most of the week doing hands-on experiments with us.  We had a theme for each day.  The first day was all about balloons....This is one of Sharko's favorite experiments.  Instead of writing the experiment, we decided to write and post a small video of it.

We all love balloons right.  If you have a balloon and a stick (say bbq stick), what can you do to have fun?  Try this at the next birthday party you go to.


Take the balloon and blow it up.  Then tie it so the air doesn't escape.  Tell everyone that you are going to put a stick through the balloon without making it pop.  Then poke the stick from one end to another!!!  Presto!  You have a balloon kebab!.


 If someone says, can you poke a stick on the side of the balloon and not at the ends?  You say, Why Ofcourse I can!.  Then ask someone to give you some tape (clear tape is even better).  Take two pieces of tape and put it on the side of the balloon in the shape of + on both sides.  Then poke the stick from the middle of the two tapes on both sides.  Here's a video to watch how that works.
