Guy Finds A Redneck Life Hack Under The Floor Boards Of His Uncle's House

1.

This guy's uncle recently bought a few acres and a "house" up the mountains. Trying to renovate the shack they discovered lots of beer bottles under the floor boards.

2.

There was also a lamp and a thermometer facing towards the bottles. They just threw them out, but the bottles were full of something that wasn't beer. The previous owner said it was anti freeze and calcium, so the guy kept asking- what the fuck?!?

3.

The answer was unexpected- it's a redneck engineering low cost heating/ AC. It's said to keep it cooler in the summer and warmer in the winter. What do you think, would you keep it? Or just buy AC?
