Instructions
Fill the glass with hot water.
Place the glow stick in the hot water for 1 minute.
Remove the glow stick and dry it with a towel. The warmer temperature will cause the glow stick to glow brighter.
Place the glow stick in the freezer to temporarily stop the chemical reaction inside the glow stick. When you remove the glow stick from the freezer, it will begin to glow again.
