Learn how to make giant bubbles at home!
A bubble is a thin film of soapy water that has 3 layers: a thin layer of water molecules sandwiched between 2 layers of soap molecules. In this mixture, the glycerin slows down the rate of evaporation of the water from the solution and makes the bubbles bigger and stronger. No matter what shape a bubble has initially, it will always try to become a sphere because it minimizes the surface area of the bubble, and requires the least energy to achieve.
You will need:
large clean bucket
glycerin (available at your local pharmacy)
dowels or sticks
string or twine
- Add 10 cups of distilled water to a large clean bucket.
- Slowly add 3 cups dish soap and 4 tablespoons of glycerin to the water.
- Gently stir mixture together trying not to create foam or bubbles in the process. Skim off any foam that does form.
- Cover bucket and set aside for at least 24 hours to allow ingredients to fully dissolve in the water.
- To make bubble wand, cut 2 pieces of string, 4-feet long and 2.5-feet long.
- Tie both pieces to the end of 1 dowel.
- Thread a washer on to the longer piece of string and then tie other end of each piece of string to the end of the other dowel.
- When holding dowels up with ends about 2 feet apart, the string should form a triangle shape with the washer hanging at the bottom.
- Dip the bubble wand into the bubble solution, making sure the string is soaked.
- Slowly draw the ends of the wand up and open while blowing air into the resulting soap film. A large bubble with form!
