This activity combines two things that kids love: bubbles and science experiments!
Here is what you need make your own super bubble solution:
Materials
- 1/4 cup dish soap (the blue Dawn brand soap works best)
- 1 tablespoon glycerin (available in pharmacies)
- 2 litres warm tap water
- 1 large container
- Pipe cleaners
- Optional: rope and two wooden dowels (to make giant bubbles)
- Optional: small airtight jars or bottles so that each child can take home some bubble solution as a party favour
- Kitchen utensils (optional, but useful if you have them on hand): funnels, measuring cups, measuring spoons, serving spoons, etc.
Instructions:
Before mixing the ingredients, it could be interesting to ask the kids about their preconceptions about soap bubbles. Here are some examples:
- Ask them to make up hypotheses about why bubbles burst
- Talk about how soap is used in everyday life
You could also take the opportunity to talk about fractions:
- “How many cups are in two litres of water?”
- “We are going to use 1/4 cup of soap for every 2 L of water. How many litres of water would I need if I wanted to use a full cup of soap? Does your answer keep the proportions of the solution the same?”
Mix all the ingredients and let the solution rest for best results. While you wait, the kids can make their bubble wands out of pipe cleaners.
If you want to make giant bubbles, simply tie two pieces of string (one short and one long) to two wooden dowels with holes at the ends. Fill a large bucket with the bubble solution and dip the string in it. Instead of blowing through your giant bubble wand, you will have to run around with it to make bubbles with the air resistance.
