Answer
Store the glowsticks in a refrigerator before conducting the reaction.
Explanation
## Step 1Glowsticks work on the principle of a chemical reaction that is triggered when the stick is bent. The bending action causes two chemicals inside the glowstick to mix together, initiating a chemical reaction that emits light.## Step 2The speed of this chemical reaction is influenced by the temperature. The higher the temperature, the faster the reaction. This is because the molecules move faster and collide more frequently at higher temperatures, leading to a faster chemical reaction.## Step 3Keeping the glowsticks in the refrigerator before conducting the reaction slows down the reaction. This is because the lower temperature in the refrigerator reduces the kinetic energy of the molecules inside the glowstick. ## Step 4Lower kinetic energy means the molecules move slower and collide less frequently, which slows down the chemical reaction. This means the light from the glowstick will last longer, in this case, more than ten hours.
