6-PC GRAVITY HAMMER ACCESSORY

The Hubelino Gravity Hammer Accessory adds exciting action to marble runs by giving marbles a powerful boost—even sending them back up several levels. When a marble hits the hammer, a metal ball swings down to knock it forward with momentum. Fully compatible with other building block systems, this 6-piece set encourages hands-on STEAM learning by exploring gravity, motion, and acceleration. Made in Germany to high quality standards, it’s a fun and educational add-on for creative marble run builds.
