Show the force a magnetic field exerts on a current carrying wire. Use this effect to measure the strength of the magnetic field at the center of a solenoid. This accessory can be added to the Air Core Solenoid to measure the force experience by a conducting loop carrying an electric current when it is placed in a magnetic field. The kit consists of the following items: 16.5 cm balanced, printed conductive blade, bounded by a conducting loop, that is wired to two conducting axles and two alligator clips which are used to connect the device to the Air Core Solenoid.

Our Electric Field Apparatus is designed to show the lines of an electric field produced by a large electrostatic charge, such as the one generated by a Van de Graaf Generator or Wimshurst Machine. The cost effective apparatus is great for classroom use because it can be placed on an overhead projector for viewing by an entire class. Included: (1) electric field apparatus (plastic petri dish on acrylic base with feet and terminal pillars), (1) bottle of castor oil, (1) packet of iron filings, (2) point charges, (2) charged plates and instructions

The path of least resistance can often lead to complications and unexpected outcomes. This is certainly true of our creatively named "Lightning Leaper". We provide an insulating plate with two binding clips on either end for connecting to a Van de Graaff generator. On the plate's surface, an incomplete metallic path-with eight small gaps-is drawn in a zig zag pattern. Anyone can see that the shortest path between the binding clips is definitely not the metallic path. Yet, the discharge from the Van de Graaff follows just this path-watch as the electricity leaps over each gap! This plate can be suspended from an insulating stand and connected at either end to a Van de Graaff generator. For hardier souls, it can be held in the hand close to the active Van de Graaff. For maximum "bang", try in a darkened room.

Demonstrate the relationship between pressure and temperature with our classic 15-070 Drinking Bird! The laws of physics come alive when our low pressure glass bird dips his head for another drink. He will keep on drinking until he can no longer wet his beak. As the water evaporates from his head, the cooler part of his glass body draws the liquid up to his head. This makes him tip down for another drink. MSDS available upon request, contains dichloromethane.

Leslie's Cube demonstrates heat absorption and radiation. The cube features four sides with different finishes: Flat Black Gloss Black White Shiny Tin The top of the cube is fitted with a rubber stopper with a hole for the insertion of a thermometer (not included). When a lamp or other radiation source is shined onto the differing sides, students can investigate the varying properties of surface finishes by measuring the rate of heat absorption in water inside the can. They may then measure the rate at which heat is released from the cube through a given side. The thermal difference between the sides may be as great as 20 times. The cube is 4 inches on each side.
