Step 1: Materials
-1 UV LED light
-1 47ohm resistor
-3 1.5v button cells
-Blue food coloring
-All purpose glue
Step 2: Step 1; Removing and Sanding the Cap
Sand down the whole top of the bottle cap and less on the sides to make it look more rustic. This can be done before or after removing the cap.
Step 3: Step 2; Creating the Light
Take the resistor and tape it forming a square to the bottom of the 3 batteries leaving the rest of the resistor to form a straight line along the sides of the batteries.
With the side of the resistor that is straight, tape one leg of the LED light to it and the other leg of the LED light to the flat side (top) of the batteries.
The LED light should glow.
Glue or tape this combination of the LED light, button cell batteries, and the resistor to the underside of the bottle cap.
Step 4: Step 3; Labeling and Filling the Bottle
Fill the bottle with water leaving approximately an inch of air from the top.
Put 3-5 drops of blue food coloring making the water turn a light or medium shade of blue.
Step 5: Step 4; Placing the Cap and Finishing
If the LED light, batteries, or resistors get wet due to the water, they will not short.
Now you can use the finished product to decorate any room how you choose.
Whenever the LED light goes out, replace the 3 button cell batteries and your Nuka-Cola will continue to glow.
