Speaker 1: Welcome to brain Stuff Frondhouse, stuff works dot com where

7
00:00:19,200 --> 00:00:30,360
Speaker 1: smart happens. Hi. I'm Marshall Brain with today's question, how

8
00:00:30,400 --> 00:00:33,800
Speaker 1: do they create the hopping cars you see in the movies?

9
00:00:34,520 --> 00:00:37,680
Speaker 1: These cars are known as low riders, and they seem

10
00:00:37,720 --> 00:00:41,560
Speaker 1: to be most popular in southern California. A low rider

11
00:00:41,760 --> 00:00:45,479
Speaker 1: is any car that has modifications allowing it to ride

12
00:00:45,720 --> 00:00:48,479
Speaker 1: very low to the ground. The problem with a low

13
00:00:48,640 --> 00:00:52,120
Speaker 1: rider is that things like speed bumps and rough roads

14
00:00:52,159 --> 00:00:57,440
Speaker 1: can make driving difficult. To solve these problems, lowrider enthusiasts

15
00:00:57,440 --> 00:01:02,480
Speaker 1: install hydraulic lift kits that allow a completely adjustable height

16
00:01:02,520 --> 00:01:06,680
Speaker 1: for the vehicle. These kits use electric hydraulic pumps and

17
00:01:06,760 --> 00:01:10,800
Speaker 1: normal hydraulic cylinders to raise and lower the vehicle. It's

18
00:01:10,840 --> 00:01:15,000
Speaker 1: pretty involved installation and can cost several thousand dollars. So

19
00:01:15,040 --> 00:01:18,680
Speaker 1: the hydraulic kits solved the height problem. What happened next?

20
00:01:18,840 --> 00:01:23,560
Speaker 1: Was unpredictable and amazing. Someone at some point realized that

21
00:01:23,600 --> 00:01:26,800
Speaker 1: with enough power, the hydraulic system could make the car

22
00:01:26,959 --> 00:01:31,680
Speaker 1: hop low rider Hydraulic systems quickly evolved to make hopping

23
00:01:31,800 --> 00:01:35,640
Speaker 1: more and more interesting, until cars could eventually hop six

24
00:01:35,680 --> 00:01:39,520
Speaker 1: feet off the ground. Originally, there was one twelve volt

25
00:01:39,640 --> 00:01:43,480
Speaker 1: or twenty four volt pump driving all four wheels in Unison.

26
00:01:43,920 --> 00:01:47,160
Speaker 1: It's now possible to find cars that have four pumps,

27
00:01:47,240 --> 00:01:50,840
Speaker 1: one for each wheel, and a dozen batteries to power them.

28
00:01:51,200 --> 00:01:56,080
Speaker 1: Twelve batteries can create two seventy two volt systems. These

29
00:01:56,160 --> 00:02:00,720
Speaker 1: powerful systems or what you see in the movie. Be
