Will the balls reach the bottom at the same time? Or will one be faster?



Make your predictions and place the two marbles behind the acrylic start tool. When you're ready, lift up the tool to release the marbles simultaneously and discover what happens!



A fun and intriguing physics experiment that will have people second guessing themselves and eager to see the results of the race. An interesting educational tool to discuss scientific principles such as gravity, acceleration and velocity.



Measures roughly 13" x 2.1" x 4.75" and weighs 2 lbs. Very sturdy construction using floorboard for the siding and base for extra durability and MDF to ensure smoothness on the inner paths.



Two marbles (colors may vary) and acrylic starting tool included.

Abigail ★★★★★

My kids love predicting which track will win each time, and the wooden ramps are sturdy enough for their excited hands. The clear acrylic start mechanism works smoothly to release both marbles simultaneously. It’s a simple design that really gets them thinking about speed and gravity.

Robert G. ★★★★★

The clear acrylic release mechanism makes it so satisfying to watch the marbles race. We've already run dozens of experiments trying to beat our predictions.

Avery ★★★★★

My kids argued for twenty minutes about which marble would win before we even lifted the acrylic start tool. The acrylic release is smooth enough that both marbles drop clean, so the race stays fair every time. It's become our after-dinner ritual.
