The two stage rocket goes straight up with split-second stage separation, and each stage returns to earth very gently sideways. Launch it as many times as you want.

If you’ve already got the spin launcher, filling hose, and rotating lander payload, you need the rocket only.
You just need to supply a standard 2-litre plastic pop bottle for the upper stage, a bicycle pump or air compressor, some water, and a big open field.

Later, you can add to your rocket by getting a third stage. All AntiGravity rockets use the same launcher and spin platform.
