My son wants to say "









That's what you get from a 12 year old!
I am a science teacher who has been working with bottle rockets for a number of years off and on. I started with a stopper type launcher that I purchased from a science supply company and a number of years ago built a launcher from irrigation tubing that continues to work well.
Mostly I have built simple single stage rockets with students, nephews, nieces and friends. A number of years ago I played around with a staging mechanism and this summer my son and I are working on it again and making better modifications.
It has been a fun summer.
