Step 1: What You Will Need
*Round coke bottle
*Switch (I prefer the 1/2 inch push button)
*Button battery with case (small size)
*Soldering Iron and Solder (mine is taped together for this instructable)
**The cost of the materials was about $3.00 not including the coke bottle. If you order the materials off of the internet, it will cost a LOT less money.
Step 2: Drill the Hole.
Step 3: Insert the Switch
Step 4: Build the Circuit
Connect the positive side of the battery to one of the switch terminals (it doesnt matter which one). Connect the negative side of the battery to the negative (short) side of the LED. **NEVER solder directly onto a battery or it may explode! Solder to the battery case WITHOUT the battery installed**
Connect the resistor to the other switch terminal and connect the other end of the resistor to the positive (long) side of the LED.
My photo isnt very good because I used scotch tape (I know better, but it wasnt permanent!) I also didnt have the resistor connected.
Second photo shows a crude schematic.
