This has got to be the most elegant geek toy I have seen since we got back from Dorkbot: it’s just a UV strobe light, shining on a steady stream of fluorescent water drips, but by tweaking the timing, you can make the drips stop, and go backwards or forwards. The most amazing thing, though, comes in the second half, where they show how you can interact with the drops, whilst also making time flow slowly, or the wrong way. Mindblowingly beautiful. I am totally making one.
If you like what I do, and you want me to do more, you can: buy my books Bad Science and Bad Pharma, give them to your friends, put them on your reading list, employ me to do a talk, or tweet this article to your friends. Thanks! ++++++++++++++++++++++++++++++++++++++++++
