Ball launcher

Here is a ball launcher for launching cat toys.  You can have your kids launch balls of different sizes and weights to see which one goes the farthest.


The smaller tube has packing tape on the end.  The larger tube has slits in the top and the rubber band is wrapped around it on one side.


The smaller tube has slits cut in the bottom for the rubber band.


Then slide the tubes together, insert a ball and launch!
