- Typically, this is a two-part reaction where the first reaction releases energy that causes a fluorescent molecule to glow. Here are some examples: glow sticks – these rely on the cyalume chemical reaction luminol reaction – chemical reaction used in chemistry demonstrations and to detect blood that glows bright blue

It isn’t absolutely necessary to understand the chemistry behind how a glow stick works, but it may help you design more advanced experiments. A glow stick is a plastic tube that contains a liquid and a glass capsule filled with another liquid. The liquid in the glass capsule is a hydrogen peroxide solution. The fluid outside the tube is diphenyl o...
Glow sticks emit light because of a chemical reaction, so the most popular glow stick experiment is testing the effect of temperature on how long a glow stick lasts and how brightly it glows. Start by applying the scientific method. Make observations of glow sticks and form a prediction of what you think will happen to a glow stick in a cold temper...
A glow stick releases energy in the form of light, so it is an example of an exergonic reaction. Is it also an exothermic (heat-releasing) reaction or is it an endothermic (heat-absorbing) reaction? For a fun experiment, start with the scientific method. Make observations, make a prediction, and test the prediction with an experiment. If the glow s...
Some of the coolest science experiments come from asking “what would happen” questions. For example, what do you think would happen if you mixed the contents of a glow stick and a ferrofluid (liquid magnet). Make a prediction, form a hypothesis, and design an experiment to test the hypothesis. Do you think the two liquids mix so you won’t see the l...
