I modified this from and idea my friend Rachael saw in a magazine. Here is how to make a bowling set out of old H2O bottles!
You'll need H2O bottles, a hot glue gun, mod modge, rice (or sand or beads or...) , paper and a ball.
First pour about an inch of rice into each H2O bottle. This will give some weight to the bowling set. Then hot glue the lids on the H2O bottles (H2O bottle lids are a huge choking hazard so be safe and glue them on!).
Cut paper into strips...
Don't be shy with the mod podge! You'll need a lot because of all the nooks and crannies on the H2O bottle. Dipping the paper into the water will help the paper conform to the shape of the bottle.
