So we made it.
1. Take a plastic soda or water bottle and cut off the bottom – used a serrated bread knife to start and then kitchen shears.
2. Cut a rag - we used part of an old washcloth – slightly larger than teh diameter of the cut off opening.
3. Rubberband the cloth to the bottle and dip it in a bubble solution- we used a disposable tinfoil pan and the Joy dishwashing liquid/glycerin bubble mix/
4. Have fun with the foam tubes you can make.
