They will glow super bright for 3 - 5 hours. Then, they will start to fade out but may continue to emit some light for up to 12 hours.
Inside the glow stick bracelets are two chemicals that emit light or glow when they are mixed together. Inside the glow stick bracelets is a thin glass tube, when you bend it for the first time, you break the inner glass tube. This mixes the two chemicals together. Just shake it up, it starts glowing like magic.
They are not radioactive and they are not flammable. They almost never break open, but if they do, the chemicals inside can be washed off skin and clothes with ordinary soap or detergent.
