Description
 
Have you ever wondered why a trebuchet is a popular science fair or class project?  How can a little gravity be used to fling an object so far and with such force?

The Keva Trebuchet is easy to build.  And once done, you can experiment counterweights and projectiles.  How do you get an object to fly farther?  How do you aim effectively?  What happens when you change the weight of the counterweight?

The instructions are easy to follow, and the kit contains everything you need.  No tools required.

You'll have a ball setting up targets across the room to see how far it can fling a ball.

Includes 66 planks, plus sling pouch, trigger cord, 2 balls, glue, washers and dowels.

Ages 7 and up.
