The kit makes use of an empty 1 or 1.5 L plastic bottle. The special cap, nozzle and fins supplies are attached to the bottle. An air tube and adapter are supplied to connect the bottle to cycle pump. The bottle is part filled with water and air pumped into the bottle. The pump connector on the bottle releases at set pressure and the rocket is then launched. The rocket will reach height of approximately 20 metres. The bottle and cycle pump are not supplied, all spares available. Complete with full instructions.

Design and make your own realistic rockets and launch them safely to heights of up to 100 metres. The rockets are made by rolling paper around a plastic tube and attaching a plastic nose cone. They are propelled using an electrically-controlled compressed air launcher which gives near-chemical performance but at zero cost per launch. Provides opportunities for exploring basic rocket science enhancing subject teaching in design and technology, science and maths. Contains launcher and key switch 'firing' unit. Uses any cycle or car foot pump (not supplied) and requires alkaline PP3 batteries. Please note: packs of plastic nose cones are available separately.

A pack of assorted coloured soft plastic nose cones to fit rockets made with the 21.5 mm diameter mandrels.

To fit the 21.5 mm diameter launch tube of the Rocket Factory.

This Circular Motion Apparatus comprises small DC motor mounted at the end of suspension rod and includes three different rubber balls with suspension chains. For demonstrating the laws of uniform circular motion. Instructions included.

This rotary investigation apparatus allows students to explore all aspects of rotary motion in a simple but effective way. The apparatus can be used to demonstrate: rotary motion; centripetal force; orbits and satellite motion. Investigate: how force varies with speed; how speed varies with radius; how speed varies with mass. Supplied with full instructions.
