Cool Ball Bearing Rocket!

This is called a gaussian gun. and can be seen and bought on Grand-illusions.com website. They have a video almost edzactly like this.Not nocking kip he has some great vids on here. And since he posted it first he deserves the credit for the post. Just answering the q on what it was.

How does this guy think of this stuff????

Interesting what you can do with phisics!

it works by using energy transfer, you know the toy people have on their desk's sometimes with the 5 metal balls connected to strings, its the same thing. as the first ball bearing approaches the magnet, its velocity increases due to the attractions, then when it hits the magnet its energy is transferred through all of the balls until it reaches the last one, where it propells it forward. you can make it stronger/faster by repeating the formation above with a space in between each. go to dangerously fun.com it explains it and sets up multiple ones for increased speed.

how fast does that go

they're called neodimium boron magnets

the device your making is a guase rifle (a magnetis linear accelerator) still nice work

Hello from Macedonia - Greece !!!

faster further more ammo

Excuse my maniacly humble idiocy but isn't that device technically exibiting behaviour wits technically impossible...? It's putting out more energy than you're putting into it...? Seriously... Of course I'm obviously an idiot & suggesting the impossible but if there's no hidden tricks there & there doesn't 'SEE-m' {sic} to be & that ball is shooting out with more energy than you're rolling the other in then what's the trick...? Would you please take the time & E-mail me the principles at-play there because I-have one of those plodding lateral minds & when I-see something that doesn't fit I either want to know why or why not... In this case what you did doesn't fit physics supposedly so please explain... Maybe we can scale-it up & make a ka-zillion dollars... Well... A ka-billion... Please reply & I'll take some time to think what would happen if such a principle was scaled up... I-know I'm so simple but again what's the trick & if no-trick lets make some money from it...

Add a barrel and you get yourself a rocket gun

I can throw harder than that.

how many ball bearings didja lose?

Did this as a sci-fair project one year. I had like 3 magnets as a chain-reaction sort of thing though.

why does this work?

where do you get the magnets

That was cool- but couldn't anyone do it? I mean it is't so speical. But it is cool.

very nice

These types of magnets are not made for impact so be warned that you have a chance of shattering or chipping

I like!!!! :):):)

go to dangerously fun.com all one word to find this and some other cool stuff ;)

4 rocket...fucker

Simkple laws of momentum trick.
Momentum before impast = Momentum after impact.
Mu = Mv

nice trick

a previous video on Metacafe called Metal Storm. It is a military application of this theory. Pretty cool because you can fire up to 1 million rounds per minute.

HOw does it work?

Good one

Cool. Thanks, kipkay.

See this cool video,click on this link!:

amazing!!

i don't get it.. any geeks around to tell us what's happenin'??

Metal Storm is actually based off of using electronics to fire projectiles, while this uses simple kinetic energy. the magnet attracts the ball, and when the ball hits the magnet it transfers its kinetic energy to the magnet, and therough the ball bearings until it reaches the last one, which shoots out. As far as it not being a high velocity, think about if that magnet was a high powered electromagnet .....
