LEARN AND HAVE FUN WITH THE 'ELECTRICITY THEATRE' Bells that ring without touching them, candles that go out with a metallic wand without the need to blow, jumping rings, electric arcs that cross space, and neon tubes that light up on touching their ends. These are some of the experiences the general public can discover as of Friday 13th November in the Science Museum with the new activity, “Electricity Theatre”.

The City of Arts and Sciences’ scientific director, Manuel Toharia, presented this theatre and explained that it pays tribute to electricity “through a series of surprising experiments that will awaken people’s curiosity, and which attempt to improve their understanding of concepts related to physical phenomena that produce electricity.” These phenomena, as Toharia points out, “may be everyday phenomena, but even so they are astounding”.

A typical example is that of lightning. Bolts of lightning occur when the most “charged” layers of the atmosphere and of the Earth’s surface transfer electrical energy. And there are more examples. We use electricity every day. In many cases we hardly even notice, but it is there when we switch on the light, when we heat something up in the microwave, and it is essential to make means of transport work.

The Museum’s first floor is housing this “Electricity Theatre” where, in front of an auditorium with an audience of fifty or so and on a stage that simulates the laboratory of a scientist/inventor, a scientific entertainer will literally be putting people’s hair on end with different demonstrations.

Electricity surrounds us and is also inside us: the nervous system, for example, works with electrical impulses. It is hard to imagine a world without this form of energy, which has become one of the most important ones for technological development due to the ease of producing it and its great amount of applications.

A new demonstration of “Science on Stage”
All objects give off energy in the form of heat, even ones that are very cold. These and many other curiosities will be revealed in the new “Science on Stage” demonstration, thanks to an infrared camera where the public can see for themselves.

The visitors can also observe how heat travels from one object to another, as well as the difference between cold-blooded animals and hot-blooded ones, with the help of a bearded dragon, and see their image in the infrared spectrum.
