Cover a carboard tube or toilet paper roll with duct tape.
Add a strip of red tape to the top.
Repeat steps 1-2 so you have 6 covered rolls.
Cut out numbers 1-3 from a Duck Tape® Sheet. You will need one #1, two #2 and three #3. This is optional if you want to add a point system to your game.
Stick your numbers to the front of the rolls from step 3.
Make a ball out of tape. Continue covering your ball until the bowling ball is the size you want.
