Instructions

1. Get a straw and carefully cut the end into four
2. Push the ends out so they look like a flower with four petals
3. Dip the flower in soapy water and gently blow through the straw

Results and Explanation

The petals help the bubble to become big by holding the soapy water in the petals so the bubble doesn't stretch too thin and burst.
