Waterslide Marble Run

The Marble Waterslide! Huh?

We love this thing, but we’re not sure we would have gone with Waterslide Marble Run as the name. Looks like a marble run to us. We guess if you run the marble straight into the tub, then sure, it’s a waterslide—and let the fun begin! Comes with (33) interchangeable pieces for different waterslide…uh, marble run…designs, and (2) marbles. The kit demonstrates basic physics concepts like momentum, gravity and speed in a fun, engaging way. You can stick it to the tile next to your tub with the included suction cups so by golly, we guess it’s going to end up being a waterslide after all! Pieces are bioplastic and packaging it made of 100% recycled paper. Designed in Australia, where water goes down the drain in the opposite direction. Or does it? Discuss. Ages 3+.
