This is a super tiny pocket sized coil gun! Although this is not the most powerful coil gun, its size and looks make up for it!

Step 2: Making the Frame

I put  a frame into the gum pack to give it some extra strength and make it easier to pack everything in the small space. Basically, I measured the gum packs dimensions and cut out some sheet acrylic to the correct measurements and super glued it all together. Once your frame is complete, move on to the coil.

Step 3: The Coil

     To make the coil you will need a small tube, an ink tube from a pen works well. Simply clean the tube with a q-tip and and start wrapping your coils.
     Once you have your tube ready, tie a half knot with the wire onto the tube and super glue it in place. The position of the knot should be about 1 inch from the end of the tube. Now start wrapping the wire around and around the tube toward the other end. Try to get a nice tight fitting coil, and keep wrapping until it is about 3/4 in. long, then apply a coating of super glue to the coil. Now you have completed the first layer! I found that 7 layers works pretty good for this compact coil gun. To make another layer, simply start winding the wire back to the knot where you first began. Keep winding until you have about 7 layers, remember to glue each layer as well. This takes some time so don't try to hurry it because the coil is one of the most important parts of the gun.

*Important Note* Do not change the direction you wind the coil, exp. if you start winding clock-wise do not switch to counter-clock-wise.

Sir, you are a genius. What brand of camera did you use?

What kind of disposable camera did you use? The brand name would really help.

Can I solder the coil leads to where the flash was?

Hello! I was wondering if I need to use the red magnet wire for the coil or if I could just use 24 gauge copper wire?

I have a question can you hook your brain up to my computer without frying either of the two, so i may copy some of your BRILLIANCE to my hard disk?

Is this achievable if i only use parts from the disposable camera?
Do you think i can do this without soldering?

you may be able to, size will be a problem though. but its worth a shot! if you cant fit it into a gum thing maybe try an Altoids tin
Will definitely be making this soon. What size acrylic did you use?
Cool! It's nice as a spy weapon too!
