Installing washing machines is not always the most pleasant task. Often, they contain concrete blocks that keep them from flinging around during a rapid spin cycle, which makes them one of the heavier appliances in your home. In spite of being practical, the weight of these machines creates a burden on the environment in multiple ways, but a group of researchers at Nottingham Trent University recently discovered an interesting solution: Plastic.
Instead of using a concrete block, a chunk of hollow plastic is placed at the bottom of the washing machine. It weighs only 6.5 pounds compared to a concrete block that averages 55 pounds, significantly reducing the weight of the machine. How can something that weighs this little prevent a washing machine from shaking? Easy: It’s filled up with water after the unit is installed.
Dylan Knight, a 22-year-old undergraduate that’s part of the three-man research group, explained in the university’s report how the plastic was able to counter the fast speeds of a washing machine’s cycle. He also explained how there have been plenty of issues with using concrete in the past.
