1 LASCELLS GYROSCOPE WHEEL -NEW! The Gyroscope Wheel teaching aid, from Lascells, provides an unforgettable demonstration of gyroscopic motion, including precession, angular momentum and torque. Includes pull cord to access high angular velocity, and bungee cord to enable the demonstration of gyroscopic precession. A question every physics student should know the answer to, is ‘why does a bicycle wheel stay upright when in motion?’ Explain this, and more with the Lascells Gyroscope Wheel. Get the wheel spinning at high-speed using the 4-metre-long pull cord to demonstrate torque, gyroscopic precession, and angular momentum. With two options for the radial placement of masses, the effect of mass distance from rotation axis can be examined. Additional masses can also be added (available separately). Can be used in conjunction with the Rotary Table (FMD-400-100) to perform the classic and unforgettable conservation of angular momentum demo, as an exciting and effective way to teach rotational mechanics.

2 LASCELLS ROTARY TABLE -NEW! The Lascells Rotary Table is a strong turntable suitable for rotational motion demonstrations. Constructed from two 18mm plywood platforms covered in non-slip matting, with 20cm bearings in between, the turntable can support balanced loads of up to 100kg and is most effectively used to demonstrate conservation of angular momentum. An effective demonstration is to place the platform on top of a stool and get a student to sit centrally on the platform, so that they can be rotated with their legs moving around the outside of the stool. If they are then rotated with arms held into their shoulders (with a 1-2kg mass in each hand for better effect), once the platform is up to speed, they can then extend their arms outwards. The rotational speed will decrease as they extend their arms and increase again when the arms and masses are brought back inwards. Examples of this include ice skaters spinning, competition divers on high diving boards, or playground roundabouts. In each case, angular momentum has to remain constant, so if the effective radius of the mass is reduced the angular speed has to increase to compensate. Platform dimensions 40 x 40 cm.

Also included are a special cap, nozzle and fins that can be attached to the bottle. The pressure tube is connected to the adaptor, which in turn is connected to a cycle pump or foot pump. The bottle is part filled with water and air is then pumped into the bottle. Once the pressure inside the bottle reaches a set level, the pump connector on the bottle releases and the rocket launches into the air, reaching heights of around 20m. Supplied with instructions. Spare tails units and pressure hoses are also available. Please note: Bottles and pump are not included.
