Almost crowned myself in front of a group of preschoolers today when a bottle rocket decided to launch itself.
Safety first.

I have the option to include those towards the end of the flight and space classes I'm teaching this semester, but we'll be in winter proper by the time we get to it ... So I'll probably elect to not deal with water rockets when it's freezing outside.

At least your bottle incident wasn’t as bad as this guy’s:

I should totally get one of those rockets for my girls. They'd get a total kick out of it.

They’re a lot of fun, you use a regular plastic bottles as the rocket. Protip, a Pellegrino bottle will withstand at least 90 psi.

I was wondering if a person could make their own. I vaguely remember seeing homemade ones when I was a cub Scout. I imagine a 3D printer could help in fabricating parts for the base.

You could make one pretty easily with a few fittings from a plumbing depart ment.
