Effect Glow in the dark products absorb light and glow in the dark. Another name for glow in the dark is Phosphorescence or fluorescence. It means that the product absorbs light and releases it back into the dark. This is possible with phosphorus, but also with newer chemical compounds.
If it is not dark enough, the glow in the dark products does not work properly. It has to be very dark in order to get a good effect. Depending on the quality this process may persist for a number of minutes to a few hours.
