He Made a Hot Tub Out of Junk Parts! ???????? #shorts #shortsvideo - Video

This guy turned an old car radiator into a hot tub heater—right in his backyard. He placed the radiator over a fire, then hooked up two pipes and a small water pump. The pump pulled hot water from the radiator straight into the tub... while cooler water from the tub flowed back into the radiator to get reheated. It created a constant loop—fire heats the radiator, the radiator heats the water, and the pump keeps it all moving. With just some scrap parts and smart thinking, he built a backyard spa that actually works.
