Video: Make water drops stand still, slow down, reverse.

It all started when my friend Jesse told me that if you get a strobe light fast enough, you can make it look like dripping water is going in slow motion or even backwards. This phenomenon happens because strobe lights can 'capture' an instant in time and allow your eyes to see it as lasting longer than an instant.

So if the strobe light captures consecutive instants of time just out of sync with a periodic occurrence such as dripping water from a faucet, it can appear that the drops are moving slowly or even backwards.
