Snap Circuits Junior 100
Award winning Elenco Snap Circuit Kits are the very best electricity and electronic kits available. Have a snapping good time learning about electricity with the reusable circuit components that simply clip together with a press stud.

An ingenious and entertaining way to demonstrate Newton’s second law of motion. Have students predict which ball will hit the floor first. Then have them close their eyes and listen. Much to their surprise, both balls hit the floor at precisely the same instant! This is amazing since one ball falls straight down while the other is propelled horizontally first. 

The compact design makes it easy to set up and operate. The spring-loaded release arm assures simultaneous release of the balls for predictable and repeatable results.  Comes complete with a set of matched balls and operating instructions.
