- 5 gallon bucket with a lid
- Spray bottle
- A few rags or old towels
- Several medium and small containers
- Four gallons of water
- One bottle of glycerin
- One medium bottle of Dawn dish soap
- Absolutely NO stirring. Stirring adds air and air is the mortal enemy to a bubble. This also gives you a sudsy solution and it is hard to blow a good bubble.
- Everything must be wet: spray the tables, children’s hands and any “tools” with the water bottle. A bubble pops when it touches anything dry.
- Squeegee off the tables into a bucket after the experiment.
- When the time comes to wash the floor afterwards, DO NOT use soapy water. It will just become insanely sudsy. Use vinegar and water. Vinegar cuts the bubble solution.
- When trying to get students to understand or try something, don’t give students direct orders unless it is a safety issue. Pose it as a question to guide them and let them experiment to figure out the answer for themselves. It means so much more! Example: What would happen if you____________? How would your bubble change if you _______________? What could you do so that your long sleeve shirt doesn’t pop your bubbles?
- Experiments must be done INSIDE! While from the practical stand point of clean up, it seems this should be an outside activity; there are too many factors that interfere with the experiments: especially wind, dry air and sun.
