The Wrecking Ball by Keva is a wood contraption you build yourself. Much larger than it appears on the box, it is nearly 3 feet high once assembled! All you need to do is follow the blueprints and use the wood glue (included) to put the wooden planks together. Once built, turn the winding drum to adjust the hoist rope for maximum impact. This kit provides physical and visual examples of pendulums and the effects of energy in motion. The boom arm is removeable, allowing for easy storage.
Recommended Ages: 7 and up.
