Awww look at those kids riding in a dangerous contraption. They really take after their mother.
"Got this car at an auction for 50 bucks. The solenoid was bad so, using items we found in the car, we made this. You turn the key, lower the arm onto a metal plate (the handle has rubber under the duct tape), and once the car turns over you lift the handle and you're good to go. The blue plastic is actually part of the interior of a different car that was in the back seat."
Well, look on the bright side: you totally got your money's worth!
