Step 1: Materials
Smart water bottle since it's probably the smoothest bottle out there for our purposes
rubbing alcohol (optional)
Solid copper wire
LEDs-color of your choice
spray paint-colors are your choice
box large enough to hold bottle (optional)
bread board to hold LEDs in place
tools: exacto knife, soldering iron
Step 2: Cutting The Bottle
Step 3: Paint Job
Step 4: Lighting it up.
Next we will drive the solid copper wire through the bottle cap and solder onto the LEDs. Power it on to make sure it works then screw it back together.
