Mix up a batch of homemade bubble solution with these ingredients you likely can find around the house

Materials:
Bubble Solution
2 cups dishwashing liquid
¾ cup corn syrup
6 cups water
Bubble Wands
Assortment of 12-in pipe cleaners
Large decorative beads
Plastic straws (optional)

Instructions:
Bubble solution
Mix in a large bucket or bowl; store in a covered container
Bubble Wands
Twist and bend pipe cleaners into wands. Make sure to add a generous loop at one end and another one at the other for a handle. Strengthen the handle by threading through a straw, or by twisting in additional pipe cleaners. You can also add beads for extra dimension (they work best on handles).
To use: Dip into solution, let excess drain off and either wave wand or blow through it to make bubbles.
