In this video we create a glow stick that pulses light.


To this we first dissolve 37mg of copper sulfate in 100mL water. In a separate container we dissolve 3.6g potassium thiocyanate, 1g sodium hydroxide and 0.2g luminol in 200mL of water. This solution is stirred until completely dissolved. Then the two solution are mixed and water is added until the total volume is 1L.

The solution may be heated to 50 celsius for improved effect.

30mL of 30% hydrogen peroxide is added with stirring and the lights are switched off. There would be a faint glow that pulses brightly every 30 seconds. I got 6 pulses before the reaction stopped.
