Mysterious Glow
There are several completely different ways to produce light. A
candle will glow thanks to its hot flame, a light bulb has a hot
wire glowing inside it, fluorescent tubes contain gases that emit
light when electricity flows through them, and an LED makes
light from current flowing through crystals. But all these light
producers mainly generate heat, and just generate light as an
incidental by-product. A light bulb, for example, only converts
about one thirtieth of the incoming electricity supply into light.
Nature works quite differently from that. Glowworms and
fireflies, as well as luminescent deep sea fish and jellyfish, emit
about 95 percent of the incoming energy as light. They do this by
getting certain chemical substances to interact, which in turn emit
light. Since no heat is produced, it is also known as cold light.
This experiment kit also
contains a chemical substance
capable of producing its own
light when combined with other
chemicals. It is called luminol,
and you can use it to perform
some exciting experiments.
