See step 3 for update.
Step 1: Supplies & Tools
Scissors (They don't need to be very sharp)
Dremel (with bit shown in picture)
Sand Paper 100 grit
Krylon Frosted Glass Spray paint
Glass coke bottle
3ft 18 gauge wire
At least one of the following LEDS: 3.7V Blue 2600 mcd 5mm 1.7V Red 3000mcd 5mm ??V White ≈2000mcd 5mm (you can find these at radio shack amount of LEDs needed depends on when you use it) (You only should need one if you use it at night)
Flux Core Tin-Lead Solder
9V battery clips (radio shack)
3 1k Ohm resistors (you really do need these and can find them at radio shack)
Step 2: Preping The Bottle
Step 3: Circuitry and Soldering
**UPDATE*** I also had a spare Nuka-Quantum cap lying around so if you have one of those you can drill holes into it and end up with the next picture.
