Johnny #5 salty experiment

Kieran got this little robot for christmas.  And he finally got around to putting it together.  I think he just didn't want to go to sleep.  Probably due to the Mike and Ike's and Hot Tamales that he had after skiing.

In any case.  It was quick to assemble.  He did it in minutes.  But it was super simple.
No batteries.
It runs on salt water.  And it kind of resembles Johnny #5 in the movie Short Circuit and Short Circuit 2 (that was filmed in TO).  Kieran's seen these movies from my era. They may not have the special effects of today, but they are still fun to watch.  He asked why there wasn't a Short Circuit 3?


In Johnny #5 head is a carbon-cloth-steel plate sandwich.  And you basically mix a salt solution and use the dropper to apply it to his head.  The galvanic reaction creates enough current to power the little motor.  I didn't expect it to go so fast.  But Johnny #5 is super light.

Neat-o.

(FYI, this is the name of the reaction that causes your car to corrode in the winter time.)
