high power LEDs
Wires (i used 22 gauge)
2 lithium ion used laptop batteries
Step 1: Building It
I cut the top off the bottle to focus the light. I taped aluminum foil to the outside of the pop bottle to focus the light. I Secured the board in the pop bottle by poking holes and threading wires through them and twisting them together on the outside.
I cut some thin cardboard and taped it around the batteries. I then paper mâchéd this box. I cut a hole for the switch. I then paper mached the bottle cap. I stuck it in the housing.
I then screwed the pop top into the housing. I put the wires through a hole I made in the pop bottle.
