Ferrofluid and Mini Weapons of Mass Destruction Contest Pictures

Sorry for the wait, but here are some pictures from the contests two and three weeks ago.

Thanks to Justin:

(1) Got it stuck on a magnet- it wasn't easy to get off, (2) In a plastic cup with a magnet under it. (3) The bottle

Thanks to Rachel:

(1) The toothpick shooter, (2) The paperclip/match shooter, (3) The mouse trap claymore- I don't have the tripwire attached to it yet and the bolt was used to tighten the rope. (4) The Air Vortex, (5) The Paperclip Trebuchet- the firing range varies a lot, (6) Shooting the paperclip trebuchet

Sorry for the grainy photos, all of them were taken with my iPhone 3G

Oh, and as you can see in the first picture, I have a little magnet in my hand, which also wasn't easy to get off... But still fun!

Cerek, thanks for posting these. It's great to see you made projects from the book. The magnetic fluid looks like lots of fun.

Sure, no problem. I had already made the air vortex before I got the book, but it's way bigger than the one in the book. I actually have three of them, two made of plastic flower pots, and one made out of a box.

That book looks amazing.

dang. you sure were busy. cool.

Yeah... you sure hit the book! And the ferrofluid looks awesome. That pic of you holding it is pretty cool. I'm guessing it was hard to get the fluid off because... well... it was fluid. Can't exactly grab it, right? Looks messy.

Yeah... I should have used an electromagnet

2 years ago I got a little ferrofluid desk toy from http://www.czferro.com/ . To this day I cant put it down :)
