Nate True has created a very interesting DIY project called The Time Fountain. The premise is simple: fluorescent dyed water through a pump with UV strobe lights. The result is a fountain that appears to have drops of water suspended in air. The really great part is that you can “interact” with the drops. You have to see the video to really understand what I’m talking about.
