Lover's Lane
Puzzler time.
This one is automotive and kind of historic. Here we go.
There was a guy back in 1935. He had a brand new Chevrolet 6. He was so excited about it so he took his girl for a ride.
So he took her for a drive across the newly opened George Washington Bridge and parked in Lover's Lane in Alpine, New Jersey overlooking the New York City skyline. Very romantic.
To make it more romantic, he turned on the radio to listen to some music. Now in 1935, radios in automobiles used vacuum tubes which had a grid that had to be heated up, in that part of the tube, for the current to pass through. And this radio drew heavily from the six-volt battery. When it came time to leave Lover's Lane, the starter would not turn fast enough to start the engine. It was cranking too slowly. And this was a problem because he had to get his girl home by 11pm.
So he started the car using the only tool he had in his possession, a pair of pliers.
And the puzzler is, how did he do it?
