Project Mc2 CO2 Rocket Kit

Tinker like you mean it with Camryns Project Mc2 CO2 Message In A Bottle Rocket!
Add some baking soda to the rocket body, then fill the no-mess rocket tip with vinegar and squeeze into the rocket body. Stand back and watch as the vinegar activates and creates a chemical reaction to launch your rocket up to 30 feet in the air! Refill the ingredients to do it again and again.
Decorate with stickers and markers to make it your own or write a secret note and place it in the rocket base to create your own sleuth-y message-in-a-bottle-rocket.
The Project Mc2 CO2 Rocket Kit includes a rocket body with secret message compartment, soft plastic tip, base, 4 fins, stickers and 2 decorating markers.
