Step 1: Things You Need
LED bulb(s). You can use any number of LEDs, with any of your favorite color. (I used one bulb and multi color bulb is recommended. Use water resistant one if available.)
Battery. Any good battery can be used. i used a 9v one.
A pocket sized small bottle. (I used a banana essence bottle.)
Wires. To connect battery with the LED(s)
Water. For a good look and charm.
Optionally, a tool to do some work in this instructable and sticky tape.
