Here are some helpful links from our DIY Rocket Day to try at home:
Soda Straw Rocket
Make a soda straw rocket out of regular office paper and tape. Launch with one breath.
Take it to new heights! This rocket is made from paper, a manila folder and a plastic bag for a parachute. Launch by jumping on a two liter soda bottle.
Soda Bottle Rocket:
To the tops of trees and beyond, launch one and two liter soda bottles using a bicycle pump on homemade launching stations. Lots of variations to try! (Please note: There is a danger of getting wet!)
