Coil Guns

     So I'm in this nerdy kind of thing called Governor's School. I'm sure some of you have heard of it, anyways, we're pretty much done with the learnings so we're messing around with all the stuff at our disposal. 
This is a nerdy post, so if you don't like knowledge gtfo. Save yourself the trouble. =) 
We're making coil guns, basically an electromagnet powered projectile. 
We took the circuit boards out of disposable cameras and removed the capacitors to have a huge storage space for our gun. 
Then we soldered all of the capacitors (10 in total) together and charged them up. I'm not gonna lie, I suck at soldering, shit took forever. I also ended up researching if getting shocked multiple times caused doesn't. *-*
Anyways, we charged these bad boys up and used a hollow pen  to make the gun and wrapped a copper wire around the bottom of it with a shit load of wrappings to get an awesome magnetic field around this sucker. 
End result: a tiny little bink that hits the ceiling and gently falls back down, enough to make a middle schooler find out his body now makes fluids. 

tl;dr - I made a gun with Physics. 


  1. I like!! electromagnetism and physics like this interest me!!

  2. It's amazing. This stuff blows my mind every time.

  3. That's actually pretty cool. Aha nice blog, keep it up! Following (;

  4. Really cool, we have a lot in common! Like the blog!

  5. nice man. wish I knew how to do that.

  6. I really want to make one of these now!

  7. haha nice. i made one of these once. mine was weak-sauce
