Shorting Short Batteries
If your child’s toy runs out of batteries, you could make a quick trip to a local retail store or gas station to pick up a fresh pack, but that would mean having to put your pants on and meeting strangers, two things all engineers secretly dread. Or, and this is just a suggestion, you could put your child at risk by using incorrectly sized batteries with some aluminum foil to make up the size difference and call it a day.

We’re sure this isn’t the safest solution, but we don’t exactly know how batteries work. It must have something to do with magic, but we know that this isn’t the safest DIY solution.
