You will need:

1. Foam ball small (orange)
2. Black Sharpie
3. Poly-cups

Instructions:

1. Using the sharpie, draw scary eyes and teeth on your small foam ball so it resembles a pumpkin; it will be used as the bowling ball.
2. Then, move onto making your bowling pins; again use the sharpie to create scary ghost faces on the poly-cups (make sure they’re upside down!)
