組み立て式木製カー

The base is sturdy enough that even a chunky cardboard box worked as a "body"—we just tied it on with string and it actually rolled. My kids spent an hour trying different objects, and the switch is easy enough for a 6-year-old to flip. It's a silly, fun way to turn trash into a tiny racer.

We grabbed an empty water bottle and some twine, and the car actually zoomed across the kitchen floor. It’s a clever little kit that turns random trash into a fun, rolling experiment.

My six-year-old attached an old toy train to the base with the string, and the thing actually rolled across the kitchen floor. It’s a clever way to turn random junk into a moving vehicle. Well worth the under-$25 price.
