Rocket Copters

At last a fun innovation in air-rockets!

Each rocket has a detachable 'copter blade' that when placed on to the rocket, makes it spin very slowly to the ground.

The solid tripod base and extra long air-hose means its also the safest on the market.

Experiment with different angles of flight, how does this effect height, distance flown and time in the air?

How is maximum flight affected when the copter blades are on the rockets? How much longer is the flight?

Instructions include explanations in to rocket flight and an explanation of how the copter blades work.
