How to play with fire and electricity

As the topic says (those things are easier to make than you might think):

Potato Cannon (spud gun)

How it works:

How to make one:

Coil Gun (Gauss Gun)

How it works:

How to make one:
Didnt find any tutorials, but if any1 is a bit interested in elecronics should notice its simple as pie... Dont want to really explain that one here, cause its fun with around 400-500 Volts... So any1 that doesnt know electronics should stay away from it :P

Fireball Shooter (more of a gadget)

How it works, and how to make one:

Tesla Coil Music

How it works:

Making of this one is simple too... you have to get a big inductor, with a metalic top that passes throu bigger ammounts of voltage, which appears as the lightning

Btw - The inductor is making the sounds, not the lightning xP

Enjoy fun with physics ^^

Coil gun != Gauss gun.

The first one uses magnetic fields to pull a (commonly) ferric projectile. The second one uses the effect of the current going through an object to propell it along the rails.

The coil gun is the simpliest and cheaper of both. The only problem with those guns is that the intensive magnetic field jams the electronics. I don't have much experience with this guns, but a nice faraday shield should do the trick.

What's the difference between terrorism and patriotism? The colour of the flag.

I feel inspired today.

Well there's a quote, not sure from whom but I think Benjamin Franklin: "Patriotism is the virtue of idiots".

Nope... with patriotism you can kill legally

hahah, yeah, i wanna bomb NGD HQ :P
well, I just found out that physics is thebest way to spend your time (I mean things like the Potato gun), but its also a way to injure yourself

Ive burnt my face yesterday with a prototype of the gun hehe. But too see those things shoot on 500-700 meters with a POTATO (!) using only PVC pipes, spray and a lighter.... it makes you scream WIIII, belive me ^^

You have too much free time. Seriously.
