Here is a list of supplies you will need. All my prices are in Canadian funds. You can get things a little cheaper from ebay and such. But this was all bought from local
plumbing and electronics stores.
The hardest thing to find is a good tubing product. I wanted to use something that was fairly cheap, came in short lengths and had the proper strength and transparency i needed. The product i found that works best is Aqua-pex. It has writing on it with the brand and specs.. but it won't be noticeable at night , when you will be using a LED hula hoop anyway.Supplies List
