• By sketching equipotential lines along a conducting surface, and then sketching their orthogonal lines, the electric field lines can be revealed.
• Kit includes: 
• Conducting paper fastened to the base via two clamps at either side
• Varying copper poles. 
• Two 19cm long electrodes included (simulates capacitor plates).
• One round electrode with a hole inside (included).
• One full round electrode (included).
• Conductive paper (included).
• Copy paper (included).
• White paper (included).
• Power supply (Not included) and multi meter (Not included) needed.

Made from special durable Poletylan material- 3 layers- yellow, black, yellow

Dimensions: Width 29 cm Length 35 cm Height 6 cm Weight 2.5 kg

•  Demonstrates the principle of resonance. 
• Swinging one pendulum causes a pendulum of identical resonating frequency to swing. 
• Made from special durable Poletylan material- 3 layers- yellow, black, yellow

Dimensions:
Width 15 cm
Length 41 cm
Height 45cm
Weight 2.3 kg

Six different weights made from stainless steel.
Length of pendulum may be changed.

•  A tube containing cork dust or Polystyrene mini spheres, with a speaker on one end and a piston on the other.
•  Speaker has optional frequencies.
•  Moving the piston alters the length of the medium. When the length of the medium equals a multiple of half the wavelength a standing wave can be witnessed.
•  Wireless remote control (Included).
•  Altering the frequency of the emitted sound wave and the position of the piston demonstrates the wave equation .
