Besides drilling the bottle which quite a while since I was trying to be careful not to shatter it, the circuit part of this project only took about 20 minutes. When you are drilling a glass bottle make sure that you use a special glass drill bit and that you go slow and don't apply much pressure. Take a break every 30 seconds or so and brush the glass dust away, I used an air can made for computer dust. Always wear proper protection such as Safety glasses and proper face mask to make sure that you don't inhale the fine particles.
