This is one of my specialist subjects and I could go on about it for a long time, I even wrote a science show about them. This page explains the 3 simplest bubble mix recipes and includes a link to a site explaining how to make a giant bubble wand.
This is a little origami book that I put together for a birthday party. I have done my best to credit the original authors of the instructions, let me know if I missed any! It is only printable for personal use and may not be copied or printed for commercial purposes. (If you want to make it into a little booklet the cover is here.)
