You'll Never Guess What They Turned This Old Car Into

These two geniuses took a vintage Cadillac and they turned it into something you'll have to see to believe. Who knew something like this was possible?

Los Angeles-based Phil Weicker and Duncan Forrester were able to manufacture a "hot tub car" from just a plain old 1969 Cadillac, and yes, that's exactly what it sounds like: a hot tub inside of a vehicle.

The Cadillac wasn't Weicker and Forrester's first rodeo. In fact, they'd attempted the hot tub car once before, using an '82 Chevy Malibu instead. It didn't turn out as they'd planned, though, and so they went another route.

Revamping the Cadillac ended up taking quite a few years to complete. As one of the car's highlights is speed, it was the ideal model to house their brainchild.

As you can see in the photo, Weicker and Forrester had a lot to contend with when it came to fixing up and morphing this car. We don't even want to know what that grime is.

Their journey began with the joyful task of removing the interior of the car to make space for the water that would eventually take up residence there.

We don't often see plywood playing a huge role in modern vehicles, but that's exactly what Weicker and Forrester used as a frame for the model of the hot tub.

Next came the aesthetics, and what's an ingenious invention without a great color scheme? Granted, the final shade isn't completely clear from here, but trust us, it ends up looking very sharp.

You might be wondering how filling a machine, with all its electrical wiring, with water would still be considered safe, or how it might function. Don't worry, they thought of that too. Much of the work can be found underneath the car's hood.

Testing It Out

With the gutting complete, the wooden frame in place, the paint job and pool lining completed, and the risk of electrocution taken into account, it was time to test out the car.

As mentioned before, this wasn't the first time Weicker and Forrester had tested the waters of the hot tub car realm. Thankfully for them, the results were wholly different this time around.

Okay, so maybe this vehicular hot tub didn't turn out looking like that. In contrast to their experience with the Chevy Malibu though, the Cadillac proved to hold the water without falling apart or leaking.

Thanks to the way Weicker and Forrester engineered their "carpool," the engine was able to act as a water heater. This way, the water wouldn't be cooling off while on the road.

Okay, so it doesn't look like the hot tub above, but if that doesn't look like the snazziest Cadillac you've ever seen, we don't know what could beat it. Then again, we do wonder how practical the car is during the winter—at least that's not an issue in Los Angeles!

The Driver's Role

Wonder where the brakes are or how they work underwater? The driver is actually able to use a marine throttle to control the gas and brakes with their hands rather than feet. That must be interesting to get used to.

Sure, the "carpool" is pretty incredible, but it wasn't just a labor of love. Their ultimate goal is to compete with it at the Bonneville Speedway in Utah.
