Since Kickstarter has been around over the last 5 years it has managed to raise funds for a variety of interesting projects. One that just received enough funding is the Carpool Deville based out of California. The 2 Inventors started prototyping an planning for it 15 years ago when they were engineering students at McMaster university.
The carpool Deville is a hot tub in a 1969 Cadillac Devillle. The tubs pump is located in the trunk which heats and the water. They are taking aim to beat the world record for the fastest hot tub at the Boneville salt flats on August 9-15-2014. The 10k they were asking for is to cover racing costs.
