How do you make the tires spin on a rear wheel drive car?

Wait for a rainy day.

Remove any extra weight from the rear of the car, such as "dead weight" in the trunk, like a spare tire or jack.

Go to a mall with a large, outdoor parking lot.

Ensure there's PLENTY of space in front of you, and get the car going 25-30 mph as you enter a shallowly puddled area of the parking lot.

Cut the steering wheel HARD (either direction) and FLOOR the accelerator.

That should do it.

IMMEDIATELY LET OFF THE ACCELERATOR.

STEER INTO THE SKID.

Remember to breathe.

Smile. You have just survived a "controlled skid".

Repeat as necessary.

Let's hope you remember this when it happens in the snow or on ice, on a mountain road at night.
