Hi.

I'm Marshall Brain with today's question, how do they create the hopping cars you see in the movies?

These cars are known as low riders, and they seem to be most popular in southern California.

A low rider is any car that has modifications allowing it to ride very low to the ground.

The problem with a low rider is that things like speed bumps and rough roads can make driving difficult.

To solve these problems, lowrider enthusiasts install hydraulic lift kits that allow a completely adjustable height for the vehicle.

These kits use electric hydraulic pumps and normal hydraulic cylinders to raise and lower the vehicle.

It's pretty involved installation and can cost several thousand dollars.

So the hydraulic kits solved the height problem.

What happened next?

Was unpredictable and amazing.

Someone at some point realized that with enough power, the hydraulic system could make the car hop low rider Hydraulic systems quickly evolved to make hopping more and more interesting, until cars could eventually hop six feet off the ground.

Originally, there was one twelve volt or twenty four volt pump driving all four wheels in Unison.

It's now possible to find cars that have four pumps, one for each wheel, and a dozen batteries to power them.

Twelve batteries can create two seventy two volt systems.

These powerful systems or what you see in the movie.
