Vomit Rocket?

In Thursday's class we looked at an example problem regarding a bottle rocket. Lucky for us, the guys at Minute Physics have already put a video together explaining how rockets work. They also help you to figure out whether or not you could turn yourself into a vomit fueled rocket propelled person.... Probably lot as beautiful as watching a shuttle launch, but theoretically it would work!
A vomit rocket sounds pretty messy, but a 2L bottle fueled with backing soda and vinegar could probably get off the ground. For an extra credit opportunity see if you can design and execute a baking soda rocket. Document your experiment with video or pictures so we can share it on the blog and feel free to work with others. Just be sure to wear safety goggles and work under safe conditions!
