I needed a Halloween costume... So I made an Arc Reactor!

I made an Arc Reactor prop for my Halloween costume this year.

Info:

Parts used:

8 White LEDs
1/2 Watt Resistor
3 AAA Battery Pack
3 AAA's
Basic on/off Switch
Circuit Wire (20 gauge but I would've used thinner if I had it)
Soldering Wire
Hot Glue
2 Pringles Lids stacked ontop of each other with a hole cut out of the middle of both of them, then the gap between them filled with hot glue to diffuse the light
Copper Wire (to create the "electro magnet coils")
Black Electrical Tape
Metal Mason Jar Insert (this is the back plate of the reactor, I found a cool looking one at Target that happened to be the right size)

Tools: - Soldering Iron - Wire Strippers - Hot Glue Gun - Marker (for winding the copper wire around for the electro magnet coils) - Needle Nose Pliers

Process:

Cut a hole out of each Pringles lid, the same size
Stack the pringles lids
Tape the lids temporarily
Fill the gap between the lids with hot glue, make sure you don't get any air bubbles.
When dried, use a soldering iron to melt holes for the LEDs through the bottom lid into the glue. Be sure to clean off your iron to prevent the tip from getting ruined.
Stick the LEDs in the holes, ensuring all positive sides are on the outside and all negative sides are on the inside (this way the shorter leg, the negative one, has less distance to go to connect to the next LED)
Solder the LEDs together (all positives to each other, all negatives to each other), leaving the last LED unsoldered
Wrap tape around each electro magnet coil section (this helps block the light and also stops the possibility of your copper touching your circuitry)
Wrap or attach copper rings to each taped section
Apply your back plate with hot glue and/or tape
Solder or connect the resistor to the positive end of the last LED
Solder or connect the other end of the resistor to the positive end of the battery pack
Solder or connect the negative end of the last LED to the switch
Solder or connect a wire from the switch to the negative end of the battery pack
Mount all of the electrical components to the back of the back plate
Clean things up a bit, I added a metal ring going through a hole in the back plate so I could string a necklace through it, and you're done.
