It was an evening craft session at our patio table. We didn't have a popcorn box to make our car out of, so we used a plastic water bottle instead. We used plastic jar and plastic milk jug lids for our wheels. Carter helped push the wooden skewers through the straws. I used the wooden skewer and a knife to poke holes in the lids. Carter helped push the skewers into the holes to attach our wheels. I taped the skewer/straws to the bottom of the plastic bottle.
Since we used a plastic bottle instead of a popcorn carton, it changed our design a little. I put a straw through the hole of the balloon and wrapped a rubber band around the balloon and straw. I cut a small hole near the mouth of the plastic bottle, put the straw through the hole and taped it in place. Carter tried to blow up the balloon using the straw. Once the balloon was inflated, our car was off!
Carter thought it was the greatest and kept wanting to try it again. He also enjoyed just pushing the car around.
