Rocket Day!

On Friday, June 19th, we had rocket day! Some of the launches worked well, some had some difficulties. That's just how things are in life.

If you want to build your own rocket launcher, I based most of my design on the instructions on this website:

and the variations here:

A good video is at the Ask This Old House website:
