Improved Water Bottle Rocket Launcher, Clark Cable Tie, Metal Spring for Locking Collar

Spring from water sprinkler head prevents locking collar from slipping down & causing unintended launches. FAR SUPERIOR to plastic spring or duct tape. Cost $2, 100% reliable, easy to make, no special tools.

All right!! The pen tube was a great idea to share. I'm in the process of building my first and it doesn't incorporate the spring.. However, it will be implemented in my second,
That you, and may I say, your laid back positive demeanor reminds me of my dad and his side of the family. So thank you again.
