Base measures 12"L x 12"W x .5"H.

Lily E. ★★★★★

I filled the tray with water and my son spent a solid hour sending the balls down the routed channels, watching them splash at the bottom. The 15 pieces snap together easily enough that he can rebuild a new path himself.

Abigail ★★★★★

The routed channels are genius — my 4-year-old figured out she could pour water down them instead of just rolling the balls, and it kept her busy for almost an hour. The 15 pieces are chunky enough for small hands to stack without frustration, too.

Joseph ★★★★★

My kids have been running balls down these for hours, but the real win is how the routed channels work with water too—they’ve been pouring cups through it and watching the balls float and speed up. The 15 pieces are enough to build a decent track without taking over the whole floor.
