Colin Furze is back with another bizarre invention that will make you wonder why more mad scientists haven’t embraced YouTube yet. This time he’s turned a BMW E30 into a driveable hot tub, complete with a pair of leaf blowers used to generate bubbles, and a barbecue grill in the boot.
Not only did the BMW have to be properly sealed and waterproofed to hold water on the inside without it leaking into the drive train and electronics, it also had to be reinforced to deal with all of that extra weight. The handling was almost certainly awful once Furze got it on the road, but the bigger problem was the water sloshing in every direction, and pouring out of the car at every turn. The impractical project, Furze says, was sponsored by Google.
