  Happy/Sad Ball Mallet
Description:

A wooden mallet with a 'happy' (bouncy) and 'sad' (rigid) ball attached to each end of the head.
Notes: Bounce each side on the table to demonstrate the difference. Can also be attached to a post so that mallet swings down and hits brick. Hold mallet parallel to table and release: the 'happy' ball will knock over the brick; the 'sad' ball does not
Location:

LDR-F4. Two mallets are available.
