This demonstration illustrates absorption and fluorescence of differently coloured materials using UV light. It is also suitable for demonstrating scintillate materials and their working principle.
One of the electroscopes in the photographs suffers from static friction. Gently tap it to release the needle and you will see the needle deflecting.
Wool and the short, yellow PVC pipe are a good combination: put the wool in one pot and stir/rub the PVC pipe against the wool. Then remove the PVC pipe from the pot and transfer it to the other pot.
One of the electroscopes in the photographs suffers from static friction. Gently tap it to release the needle and you will see the needle deflecting.
This demonstration illustrates the electric field lines inside and around the capacitor.
This demonstration is an entertaining visualization of the induction of charges and its repelling effect due to opposite values.
This demonstration showcases the principles of electrostatic induction by generating high-voltage sparks and charges, illustrating concepts of electrical potential and charge separation.
This demonstration shows the behavior of sunset through Rayleigh scattering. It is a clear way to demonstrate the behavior of light in the atmosphere and gain student’s interest.
This demonstration showcases the connection between electricity and magnetism by providing an insight into the behavior of wires under electric current and influence of the magnetic field of each of them.
This demonstration showcases that Faraday’s cage can block external static and non-static electric fields. It illustrates that electromagnetic waves, which include radio waves, cannot penetrate the cage. This demonstration provides a clear, visual example of how Faraday cages work, making abstract concepts like electromagnetic shielding more tangible and understandable.
This demonstration shows how the Leyden jar can store electrical charge, which can then be discharged in a visible spark. The dramatic discharge of a spark can engage audiences and stimulate interest in the science of electricity.
With this demonstration, one can clearly show how coils and magnets interact together and produce an electrical current.
