EDIT: Long rubber bands or two short rubber bands tied together work much better than one short rubber band.

Rubber band
Craft stick
Masking tape

High five on slingshot rocket. Loved the details. I am a teacher in Alaska and needed an idea for Read Across America Day. I used your project with six groups, about 10 per group, kindergarten to sixth grade. We listened to the children's book Mooncake by Frank Asch and then built rockets. It was awesome. Even the little guys were successful! Thanks for putting this out there.
