Introduction: Glow in the Dark Jello!
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
*Stove
*Liquid measuring cup
*Small pot for boiling water
*Mixing bowl
*Mixing spoon
*Refrigerator
*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)

Step 2: Measure Out Tonic Water
Measure out 8oz (1 cup) of tonic water in a liquid measuring cup.
Safety: Use caution when removing the lid from the tonic water. If the water has been shaken, the lid will shoot off and overflow. Allow for the water to settle if the bottle is under pressure.

Step 3: Pour Tonic Water Into Pot
Pour tonic water into pot.
Step 4: Turn Stove Burner on High
Put pot on burner and turn on high.
Step 5: Pour Jello Packet Into Mixing Bowl
While water is boiling, pour Jello packet into mixing bowl.
Step 6: Pour Boiling Water Into Mixing Bowl
Once water has boiled, pour the boiling tonic water into mixing bowl.
Safety: Pot will be hot! If the pot is too hot to grab, use a potholder to remove the water from the burner.

Step 7: Stir Until Dissolved
Stir together Jello and boiling tonic water, making sure that the Jello powder fully dissolves.
Step 8: Add Cold Water
Add one cup of cold tap water to the mixing bowl.
Alternate method: If you would like your Jello to glow more brightly, add one cup of cold tonic water instead of tap water. However, doing this will make the Jello taste more bitter than normal.

Step 9: Chill in Fridge
Place the mixing bowl in the fridge and chill for four hours.
Step 10: Remove and Test With Blacklight
After four hours, remove from fridge. Turn out all lights and turn on the lamp with the blacklight in it. You should have glowing Jello!
