Maggie is trying to build a rocket out of an empty two liter bottle, for a school project. She taped four cardboard fins to the bottle and took it to school. They were launched in science class today. The goal was for the bottle rocket to shoot straight up. Maggies went off to the side. She got a new two litter bottle from her grandma today. The school will be launching rockets again tomorrow, so the kids have a chance to re-design their rockets. Maggie says that she needs to have a heavier cap. She is going to tape the four old fins onto the new bottle. She wants to make a heavier cap by taping a paper plate to the lid. She said that two kid's rockets flew up, everyone elses went to the side.
