Here is what you'll need................wooden dowels, wool or cotton yarn and a bit of glue. We made "child sized" giant bubble wants. The dowels are cut about 3 feet long, grown-up ones could be 3 times that size for enormous bubbles.
Tie string on and wrap around dowel 6-8 inches, this will absorb the bubble solution and keep bubble from popping. We spread a little bit of glue to secure the wool yarn.Tie on a "D" shape with another piece of yarn. Again this is a child sized giant wand, the strait part is about 2 1/2-3 feet wide, a bigger one could be as wide as the span of your arms.
I used this recipe and let it sit overnight, and made it in a bucket with a lid.
The bubbles take a little practice.
