hmmm- DIY project

I saw this on Kiddley (a new kid's craft blog) today and I think that I want to try one. She got the directions off of PBS's Zoom (their kid's site, where I got my hummus recipe that I am too chicken to try). There are also good instructions on Kiddley. I love Claire (who also does Loobylu) and I'm always lurking on her blogs. She is so crafty!
If you get a good bottle this could be really cute! This is the bottle I want to use:

I am thinking maybe some red and black buttons would be nice?
