For all those people who want an easy to make arc reactor, this is for you

Step 1: Circle

trace the bottom of your light onto the cardboard

Step 2: Inside the Inside Circle

now take a sharpie accent highlighter and trace the bottom of it on the tracing paper. flip it over. center it on the inside of the inside circle. tape it down. trace over the edges while pressing down hard. when you remove the tracing paper, a light outline should be there, just like in the last step.

Step 3: Drawing the Inside Circle

take your tracing paper and put it over your light. trace around the actual light with a pencil so you get a circle. flip your tracing paper over so the side you drew on is face down on the cardboard. then align that circle you just drew on the tracing paper with the circle on the cardboard( you could measure but im lazy) until it looks centered. tape it down. then with a pencil press down hard on the tracing paper then scribble scrabble around the circle. but before you do this make sure the circle you drew is on the opposite side ur drawing on, because if it isn't, it wont work. on the pic ignore the lines in the middle and the circle in the middle for now.

Step 4: Lines and Inside

inside that circle we just drew, make another circle any size you want. it just has to be smaller than that circle. draw a dot on the center. take your protractor, and expecting you know how to use it correctly, make a 36 degree line. keep on doing this until you have them all the way around, there should be 10. then darken them up and male them a little wider like in the third pic.if you look closely, you can see i scribbled in lightly with pencil in some spots. do that too. it will tell you what not to cut out.

Step 5: Cut It Out

tittle is self explanitory. just make sure you dont cut out what you need

Step 6: Final Touches

after you cut it out make a small rip on the outside, this will stop it from bending when you tape it. tape it to the light. i would try to get the three lights covered, i found it looked better. tape or glue some string to the back if you want a necklace. i know his isnt the best instructable but it's my first so give me a break k? i am working on a second version, i'll tell you ow it goes. please rate and give comments, i want info on what you think
