If you’re working with power tools on a wet, rainy job site, you could take the chance that your extension cord won’t trip a breaker when it slips into a puddle, but there’s a better way.

John Ross from Bethel, Connecticut is a mountain bike rider and has a bunch of flat tires sitting around his barn.

He took one of the inner tubes from those tires and made a sleeve that connects the tool to its extension cord in a water-resistant way. Here’s what he does.

I cut off an about six-inch piece of inner tube and slip one half of it on to the extension cord. Then, I fold the other half back onto itself (enough to expose the socket again). You’re going to have to stretch it over, but that’s what you want to keep the water out. Then, plug in the tool and peel the other half of the inner tube over the other part of the socket.
