Catapults

  
Want a simple machine to make with your children? 
                 Try a catapult.

It’s simply made with clothespins, tongue depressors, a piece of
wood and milk jug lids.  I glued it all together and set it out with
targets and pom poms for shooting.
 
We started using the catapult on the floor and quickly discovered
the piece of wood was too light so we needed to use one hand to
hold it in place.
 
But we learned to work together to hold it in place and still make
the pom poms go flying.
     
The next day we moved the catapult to a table and taped it down. 
But before doing that I had to staple the milk jug caps to the tongue
depressors because they kept coming off.
      
Thanks to Go Kid Yourself for this wonderful idea.
