Free fall experiments have never been easier!

Quality Lamp Receptacle.

A simple tool for communicating complex workings of electricity, this plastic battery holder is fitted with three banana plug jacks.

Smooth-running ball-bearing clamp pulley for use with inclined planes, force experiments, or demonstrations of work and machines, this durable, lightweight plastic pulley fastens to surfaces up to 18 mm thick.

Accurately measure the velocity of your dynamics cart.

Mounted on molded plastic base, the unit consists of a base into the top of which may be screwed one of a set of four vases of differing shapes. An aperture in the bottom has a thin rubber diaphragm across it, bearing upon the short arm of the lever pointer. A moveable index on the vertical rod enables the height of water in vases to be set at same level. The apparatus is mounted on moulded plastic base that measures 25 x 17.5cm. The experiment is performed by screwing in each vase, in turn, and filling with water to the same level. It will be seen that the given height of water will result in the same deflection of pointer whatever shape of the vase.

Comprised of a thick plastic base with four rubber feet, along with with an 18cm diameter aluminium plate with an insulating handle.

Ideal for studying collisions in two dimensions, these pucks can be supported on plastic beads or levitated with air from the balloons to reduce friction. Use on any smooth, flat surface. The pucks measure 10 cm in diameter, and one puck is twice the mass of the other two.

Economical pulley for simple machine experiments.

A set of eight coils wound on individual plastic spools. Each coil has two binding posts.

This unique metal launcher has multiple settings, so launch speed and angles may vary.

Pieces of reusable zinc-plated iron wire for magnetic field experiments.

This model shows the internal structure and operating principles of an air cooled two-stroke engine. All parts are aluminum and plastic. Ignition is shown via a small bulb. Carburetor and fuel supply are also sectioned. Hand crank is provided for manual operation. Mounted on a base.
