39. A swim mobile
In the 60s in New York, a mobile swimming pool drove thru neighborhoods on hot days. This swimming pool was on the back of a large truck and filled with water. As it drove around town, children and adults climbed inside to take a dip. While it didn’t stick around for long, the idea did spread. Detroit had their own versions of swim mobiles in the 80s. It’s rumored that a new and improved version of the swim mobile is in the works in the UK and may soon be making stops in London neighborhoods.
