This tutorial will show you how to make Jello... that glows! It uses ingredients that are all edible so you can enjoy eating it after it's made! The Jello is easy to make and the longest part is waiting for it to chill. Prep time is around 10 minutes and the chill time in the refrigerator is 4 hours.
So why does the Jello glow? Quinine (an ingredient in tonic water) is a fluorescent substance. These substances absorb ultraviolet light and then re-emit it. The light emitted has a longer wavelength than the one absorbed which makes the light visible and causes quinine to glow. When you substitute tonic water for regular tap water when making the Jello, it adds the quinine which adds the glow. It is better to use light-colored Jello for maximum glow.
There are some safety consideration to address when working with carbonated drinks and hot stove-top surfaces. First of all, use caution when opening tonic water. If it has been shaken, the lid might fly off and the water overflow. Secondly, always be safe around hot stove-tops. Do not allow children around a hot stove and use caution when working with hot liquid.
Step 1: Gather Your Supplies
You will need the following:
*Jello (light-colored Jello such as Lemon or Lime will work best for this project)
*16oz of tonic water
*Liquid measuring cup
*Small pot for boiling water
*Small Table Lamp with fluorescent blacklight (The blacklight must be fluorescent and not simply a colored bulb. It can be purchased at most Wal-Mart locations for around $4.00)
