It's a micro sized version of the LHC! I built it out of trash such as bottlecaps and scrap wire pieces. It comes with miniature toy physicists, and even has photon radiating action!
Step 1: Materials
Materials: Be creative. For the main body, use whatever items you can find to create a cylindrical shape. You will want to include a small keychain flashlight for "photon radiating action." Also, decorate it with whatever old electronic parts you can find to make it look particle-accelerator-y. I found some bits of wire, ribbon cable, Christmas light bulbs, and metal discs from a hard drive. To attach pieces together, use an adhesive of your choice.
Step 2: Assemble the Collider
I first made holes in bottle caps to accomodate the flashlight. Make sure the light shines through the front. I added the metal discs (which I wrapped with some copper wire for looks) to the front. Adding more bottle caps created a cylindrical shape. I decorated the outside with wire, ribbon cable, and Christmas light bulbs.
Step 3: Stand and Mini Physicists
I built a stand by cutting and bending two mini Altoids tins into a curved shape that the particle accelerator can rest on. I glued these to a sheet of plastic. To make mini physicists, I twisted two bits of wire together into an X shape for the body with arms and legs,then added a drop of hot glue for the head. Mini engineers and interns can be made in a similar manner.
