Demonstration
Preparation: Making the Big Bubble Solution
- In a large container, mix two cups of soap with six cups of water. Mix it slowly to minimize the suds formed.
- Clear away most of the suds from the surface, and add 1/3 cup of glycerin, stirring while adding it in slowly. Once fully dissolved, store the solution in a container and label it. The solution will last about a year, but should be mixed prior to every use.
- Presentaiton
- Pour the bubble solution into several large bowls or tubs. Set the big bubble wands next to the tubs. If indoors, lay out a tarp in front of the table the tubs are on to help catch any mess.
- Let students come up and have fun! the solution can make bubbles that are several feet wide, and students will love playing with it.
