Make launches faster, easier, and more powerful with the PlaySTEAM Electric Rubber Band Winder! Designed for use with rubber band–powered airplanes, boats, and flying toys, this handy tool takes the work out of winding by delivering consistent turns at the push of a button. Kids can focus on experimenting with flight and propulsion instead of tiring their hands, while also learning about energy storage and transfer. Compact and easy to use, the Electric Rubber Band Winder is the perfect companion for PlaySTEAM kits or any rubber band science project — giving young inventors more launches, less waiting, and bigger results.
