Rain Umbrella
How can the speed of falling rain be measred with an umbrella?
i find this question in a physics book... i think it's possible
Attach a spring on the bottom of a handle, and record the contraction of a spring with a still high speed camera. Then analize the futage on your computer and mark how much the spring has contracted
