how to put a car on two wheels
Ski (driving stunt) The stunt is generally performed by driving one pair of wheels up on a ramp to lift one side of the car.[2] Alternately, the stunt can be done in a vehicle with a high center of gravity (such as a 4x4 or SUV) by turning sharply or at speed. This technique is more dangerous because there is a strong possibility of the vehicle tipping completely over. Another technique is to let some air out of the tires that will be on the ground, so that the car can tip more easily, as well as keep its balance better. Once up on two wheels, the car has to be balanced by steering (much as one would when riding a bicycle), which makes it necessary to drive more or less in a straight line.[2] The vehicle used must also be fitted with a lockable differential (common on 4x4s). The stunt was perfected and first performed at the 1964 World Fair by Tonny Peterson of Copenhagen, Denmark.
