The heart of this Chemical light is the Light Stick – used by trekkers to light their tents. These Light Sticks are used by mountaineers and can be bought in an adventure store. Cut the plastic vial and pour out the liquid which is largely hydrogen peroxide in a test tube. Then remove the vial from the tube. This tube has a pink colored liquid called LUMINOL. Break the glass tube and pour out the Luminol in another test tube. The white color liquid is hydrogen peroxide; and the pink colored liquid is Luminol. Now pour the hydrogen peroxide in the Luminol and then shake the contents well. You will be surprised to see that this mixture continues to glow in the dark like a low-watt bulb for almost eight hours. Unlike candles or lanterns this chemical light is safe and will turn burn the tent in case of an accident. This work was supported by IUCAA and Tata Trust.
