A Watched Clock Never Moves

Have you ever wondered why you don't see motion blur when your eyes flick to a new position? Why, if you sit in front of a mirror and watch yourself, you never see your eyes move? That is saccadic masking, one of the lies your brain tells to avoid confusing you. Have you noticed that the first tick after glancing at a clock with a second hand can take more than one second? No, it's not just you! That's a related phenomenon called chronostasis, or more commonly the stopped clock illusion.

Floating Water

Making water appear to levitate usually requires a strobe light to trick the eye. If you don't have a fancy system to control water flow, you can run water through a tube taped to a speaker playing very low frequency sound, and again use a strobe light to make the water appear to defy gravity. Or you can ditch the strobe, and sync the sound waves to the frame rate of a video camera to make water drops appear to hover.

Trippy optical illusion

Your daily dose of perception-bending. Stare at the center of this video (wmv or flash) for a minute or two then look away from the screen at your surroundings. You'll experience an interesting and somewhat disconcerting effect. Not appropriate for anyone prone to headaches or seizures.
