Material: Steel Ball
Size: 9*7.5*9cm (L*W*H)

Features:
Test Newton’s law of equal and opposite reaction by lifting balls from one end, letting them drop and bump the remaining balls. See what happens! The frame is plastic, but the balls are heavy enough to ensure the reaction works well.

This balance ball set is a touch of amusement. Pull one ball and release – you’ll see one ball bumping to opposite position. Looks great on your desk at home or in the office.

Package: 1 Pcs Newtons Swinging Ball
