Greek Waiter’s Tray
Catalogue No: 1040025
The waiters in Greek cafes are famous for their dexterity as they swing heavily loaded trays between tables without spill. This sturdy device illustrates this principle of rotational dynamics in a way that will amaze your class. Place a clear container of colored water on the platform of the tray and start swinging from side to side. With practice, you should be able to swing in wide circles and even upside down. The container stays put because the net force acting on it is always directed radially, toward the center. This pins the container to the tray along with its contents. Our durable wood tray doubles as a laboratory support stand and can be clamped vertically or horizontally. It includes an attached pendulum and instructions. If you add magnets to the base (not included), you can also use the pendulum to demonstrate chaotic motion.

Physics, Property of Matter Fluids
Guinea and Feather Apparatus, 16 x 500mm
Catalogue No: 1021260_1
Demonstrates that the objects fall at the same rate of acceleration in vacuum under the effect of gravity irrespective of their relative weights and sizes. Consists of a thick-walled glass tube fitted with rubber bungs at each end to seal the tube. One of the rubber bungs has a glass tube of about 8mm diameter fixed through hole in it that has rubber tubing with clip for connecting it to vacuum pump.
