1. Using the box cutter, cut out a 6" hole in the bottom of the trash can. Many trash cans have re-rounded circles you can use as guides.
2. Cut out a piece of trash bag a little bit larger than the top of the trash can. Roll up the golf ball in the middle of the bag and secure it with a small bunjee cord. Run a longer bungee cord through the smaller cord.
3. Secure the trash bag to the trash can using tape and attach the longer bunjee cord strap ends to the trash can handles.
