Build a giant-sized bubble wand and mix a special elastic solution to create massive, long-lasting bubbles. Learn how adding a binder like guar gum helps bubbles stretch without popping!

Tools

• large mixing container
• whisk

Materials

• liquid dish detergent (1 cup/8 oz)
• guar gum (1 heaping tbsp)
• baking powder (1 tbsp)
• water (16 cups/1 gallon)
• cotton string (approx. 3-5 feet)
• sticks or hanger bases (2)
• metal washer (1)

Safety

• Adult supervision required when mixing ingredients.
• Be careful not to get soap in eyes; rinse immediately with water if it happens.
• The bubble solution can make outdoor surfaces very slippery; use caution when walking.
• Adult supervision required for sharp objects.
• Do not wrap string around neck or limbs.
• Adult supervision required for children under 8.

Steps

1. Pour 1 cup of liquid dish soap into your large mixing container.
2. Add 1 heaping tablespoon of guar gum and 1 tablespoon of baking powder to the soap.
3. Mix the soap, guar gum, and baking powder together until well incorporated.
4. Slowly stir in 16 cups of water and whisk the mixture to remove any lumps.
5. To build the wand, tie one end of the cotton string securely to the end of the first stick.
6. Thread the metal washer onto the string to provide weight at the bottom of the loop.
7. Loop the string twice around the end of the second stick and tie a secure knot.
8. Lay the wand flat to form a triangle shape with the washer at the bottom point, then tie the two ends of the string together to close the loop.
9. To make a bubble, hold the two sticks together and slowly lower the string loop into the bubble solution until it is fully saturated.
10. Lift the wand out while keeping the handles together, then slowly pull the sticks apart to create a giant bubble.
