easist way to make a laser gun?

Um, not sure why you need a laser gun.  If it's to shoot things, a standard ballistic gun is more practical.  FYI, it's against international law to develop lasers weapons to shoot people.\n\nIf you mean a toy, you can always pick one up at the local toy store (see link).  You won't see the beam.  If you did, it would be dangerous.\n\nhttp://www.target.com/gp/detail.html/sr=1-4/qid=1164226650/ref=sr_1_4/602-3152398-8374206?ie=UTF8&asin=B00023C3ZU\n\n\n\nNot a satisfying answer?  OK, you can always buy this:\n\nhttp://www.engadget.com/2005/11/03/handheld-laser-gun-available-for-purchase/

How to make a simple Van de Graaff Generator\n\nITEMS:\nPlastic Tupperware (microwave oven safe)\nSome wires\nNail\nSmall DC motor \nPiece of PVC pipe (approx. 3.8 cm in diameter)\nBroad rubber band \nWooden skewer\nPlastic bag\nRoll of tape\nSoft drink can\nMineral water bottle\n2 3volt batteries\nBattery holder (optional)\n\nPutting it together:\n1) Cut a hole in the middle of the bottom of the plastic container.\n2) Glue/tape the motor to the lid, making sure the shaft is at the centre of the lid.\n3) Using a hot nail (can be heated at the stove), make two holes near each other for the wires of the motor\n4) Thread the wires through the two holes (the two wires will connect to the batteries)\n5) Cover the container with the lid. (Inverted container in this case)\n6)Make another hole, perpendicular the motor shaft\n7) Thread another wire through(this will be your ground wire) \n8) Make the appropriate measurements for cutting your PVC pipe length and grooves(where the stick will rest)\n9) To make the roller, just stick tape to your stick and go round and round and round.\n10) Place the PCV tube on the lid, perpendicular to the motor. \n11) Thread the stick thru the rubber band and place it in the grooves.\n12) Make sure both rollers are parallel to each other when you thread the bottom of the band to the other "roller"\n13) Cut the top of the soft drink can.\n14) Cut both ends of the mineral water bottle off, making sure that it isn’t shorter than the PVC pipe.\n15) Make a hole near the top of the bottle.\n16) Strip some wire, twist it, and poke it through the hole.\n17) Electrically connect the copper wire to the soft drink can.\n18) Tape everything in place.\n\nWhen you put everything together, you get a crude Van de Graaff generator. Make sure the combs (end of wires) are near the belt and rollers. Make sure that when you run it, the belt doesn't slip off. If it does, make sure both rollers are parallel to each other. Also, try to superglue the motor to the Tupperware lid.\n\nWhen you first run it try taping strips of tissue paper to the can. It should start to rise seconds after the batteries are connected. If this fails, put your finger near one of the tissue strips. The strip should be attracted to your finger.\n\nPlaces with high humidity can be a real problem for electrostatic experiments. Try working in an air conditioned room to help overcome the problem.\n\nThe last two links are the best ones and both include detailed step by step process with pictures.

This will be simple for You. Break the Gun Down. Make sure You put each set of Parts in a Different area so You wont get them Mixed up. Once you have the Firing Mechanism out put the New Pin inside the spring. Clean and oil the parts with WD-40 and use this sparingly. You only want a thin coat of oil on the Workings. assemble and oil the outside of the Rifle. I'm home on weekends and will walk You through this as Need Be. I own one Myself.

The absolute minimum you need is a laser, a beam splitter, two lenses, some mirrors, and a photographic plate. You will also need to develop the photo using conventional chemical means, which is no longer easy to have done. I'm sorry, but it just can't be done with any less than that.\n\nBut if you're still game, here's how.\n\nFirst set up the laser to go thru the beam splitter. (This is just a partially silvered mirror that reflects half the light while allowing the other half to pass straight thru.) One half of the beam will pass thru a lens (to broaden it out), and will fall directly on the photographic plate. The other half of the beam will pass thru another lens (to broaden it out) and illuminate the target object. The laser light reflected off the target must then ALSO be visible to the photographic plate. \n\nDarken the room, open the plate holder (so that the plate will be exposed) and turn on your laser. At this point both the direct and reflected laser light should be falling on the plate. When you've exposed it enough (how long? depends!) turn off the laser and cover the plate. Then you can have the plate developed.\n\nWhen it comes back from the developer, you'll be keenly disappointed. In order to view the image, you will need to shine a laser thru the plate again to make the image visible in 3-d.\n\nAdded edit: You must also make sure that the room is TOTALLY dark, and that the ONLY light falling on the plate is laser light, either direct or reflected. Also, even tiny vibrations are enough to ruin or partially ruin the effect, so keep everyone out of the house (including pets!), or do your hologram when everyone is asleep.

Hmm. . its pretty rare stuff so you are not going to hand out samples\nSince it was once used in lasers you could start your presentation with a laser light show, or just a simple laser pointer\nPresent the information chronologically, show how and why it was discovered (it started as a blank square on the Periodic Table of the Elelments) talk about it uses and why it was replaced\ngood luck

You can sell BB Gun parts on EBay.   Just take the stock or other major part(s) off and sell them seperatly as Parts.  Its best to remove a part or two that allows it to actuall shot and so it looks none funtional.

any of your leading fishing magazines will have it.\n  local fishing shops. \n  Or try a gun shop that has Reloading Supplies.\nthe same principle in making your own homemade bullets is used for melting them. Traditional black power guns especially

if you are trying to build a model - i would recommend either a playdo type creation or if you wanted to be fancy - use a jello mold.\n\nJello mold you make the mini components first and let them harden.  then put them in place in and outside of your 'membrane' and fill in with a clear jello (knox).  The clear represents your axon and cell membrane with your multicolored preformed pieces acting as your pump, na, and K+\n\nhave fun!

Make a 3d model and print it out using anim8or @ anim8or.com\n\nIf that is not in option, try using a styrafoam block and carve it.

a compound bow and carbon steel arrows should do the trick, a gun would work better though

easy. just get a regular grenade and tape a lot of airsoft bullets to it. ur mom may not let u use it near the house. my mom never lets me.
