Day 43:

Maddie and Abby skewer balloons

13 year old Maddie and Abby stick skewers straight through balloons without them bursting!

To do this they stuck a piece of tape on the balloon and put the skewer through the tape covered area on the balloon.  When they did this, the balloon didn't burst whereas if they pierced it where there was no tape it did.  This is beause the tape stopped the hole from growing by holding it all together.  Ballons burst because the hole grows quickly into a crack causing it to burst, by preventing the grack growth from happening the ballon stays inflated.
