What you'll need:

• 10 plastic pop bottles (710 mL size)
• Water
• 1+ pumpkins (be prepared with a couple of extra pumpkins as occasionally they split)

What to do:

• If you're going to be bowling indoors, you'll want to choose a place where you can wash the floor! Just in case things get a little messy.
• Rinse your pop bottles thoroughly and fill them 1/3 of the way with water. Screw the lids back on tightly and check each bottle for leaks.
• Give the player a hand-sized pumpkin. Ideally, you want to choose pumpkins that are quite hard so they'll be less likely to break apart while you're bowling. (Hint: Look for ones with a slightly greenish tinge.)
• Set up the "pins" in classic bowling pin formation.
