This is a soda bottle water rocket project I've been enhancing.
There is a base and fins.
The fins are very tight for a reason. You may need to sand them down a little.
My current rocket goes 250' up.
You will also need a soft rubber stopper, 1/4" joiner and 1/4" tubing.
I use my portable airtank and a blowgun to power it.
Others use a bike pump.
Please be careful!!! Setup a shield in case the rocket tips while pressurizing. See pic above.
