These are the largest "Happy-Sad" balls we have seen! They are 1-1/2" in diameter! These two black rubber balls appear identical, but have extremely different physical properties. Dropped onto a hard surface, one ball bounces high while the other hits the floor and stops immediately. Show students that some properties cannot be observed without experimentation. Set includes two balls (one 'yes' and one 'no').

Perfect for teaching your students about Newton's laws of motion, Newton's Cradle makes a great addition to any classroom.
