Our neighborhood had distinctive split rail fences around all the front yards, and one time, after a big snow storm, we wrapped toilet paper back and forth across the street, using the fence uprights as supports. To a driver, it looked like someone had built a wall of snow across the street.

Cars would recognize the barrier too late, hit their brakes and skid right through it. I'm sure they thought they would hit a solid wall, but then it would just silently "explode," and the presumably shaken driver would travel on, and we'd run out and wrap the toilet paper back and forth for the next victim.

This was back in the 70s, so no method of filming it, but it would have been cool.

It was harmless, but a lot of work setting up again and again, and it would only work on the perfect sunny snow day, so we never got the chance to do it again.
