Shake and Go

By Deane Barker on November 6, 2005


Shake and Go Speedway Raceway: I played with this racetrack at the local Toys-R-Us last night. It’s the weirdest thing — you pick up a car and shake it, and it goes. You can shake it for five seconds — not even very hard — and it will run around the track for about ten seconds.

But, it turns out the cars themselves need 3AA batteries each. Which leaves me wondering what the shaking is for. Are the cars powered or not?

Anyway, I sat there with this track for about 20 minutes trying to figure how it worked. Kids wanting to play with it were getting impatient. If anyone has some insight into the mechanics behind this toy, I’d love to hear it.

  1. The shaking is probably bouncing a magnet around inside a coil of wire, which in turn creates a current, which then charges the batteries. Regular alkalines are rechargeable, you just have to be careful and limit the current. The shaking probably doesn’t generate enough to make it unsafe.

    I may be totally wrong, it’s just the first thing that comes to mind.
