Painted wings and giant rings

So we had a sturdy Omaha Steak cube just hanging around, but this would work in any cooler. I filled it with warm tap water, and then added an aquarium heater and popped in a thermometer just for curiosity’s sake. It works wonderfully and keeps the water between 85-95 degrees perfectly, and it’s entirely cat proof with books on top.

IMPORTANT FOLLOW UP – THIS WAS A TOTAL DISASTER
So er, water weighs a lot, and the pressure of having a few gallons of water in this cube caused it to crack and then the water seeped through the wood floor into the basement, ruining the ceiling of the basement and rotting some wood molding below. If I were to do this again, I’d use a plastic bin with a foam cooler inside it.
