Superhydrophobic carbon nanotubes

I’ve been wanting to play with superhydrophobic (“very water hating”) surfaces for a couple years now, but haven’t found a source. Here’s a fun video done at CalTech.

    Wonderful video, love the merge! Your gallery on water droplets is second to none! I just want to run home and start the snapping…all weekend plans have been canceled 🙂

    I couldn’t wait, ran home and made an attempt at this…up until 2am…loved it and I’m now hooked. Here’s my attempt:

    I realize this is a very late reply, but if you’re interested, there are several very inexpensive ways to make/buy superhydrophobic surfaces. I’m studying them for my PhD. One easy way is to roughen PTFE sheets, another is to buy ‘Magic Sand’ which is superhydrophobic sand grains. Perhaps the simplest is to take a piece of metal and hold it in a candle flame. The soot from the flame will blacken the metal, but will also make it superhydrophobic. If you’d like more information, feel free to email me.
