[Boiling point]

I am kind of a techno-geek, and have purchased some of those "rare earth" magnets to play around with. They are awesome and expensive! One about 1.5" dia.x .5" thick is about $12 surplus price. They are actually dangerous to play with! It cannot be removed from a piece of metal without a pair of vice-grips. If you get two of them that size close enough to attract each other, any flesh between them is coming off in a very painful fashion, which will need to be relieved with a helper with a pair of vice-grips! Great for fridge magnets too, no need to stick a picture of your kid up...just stick the kid.

I picked up one about two years ago that is about 2 inches by 1 inch by 1/2 inch, about 25 bucks. The only way to get that thing off of a piece of steel is to slide it off the edge, it's gotta have hundreds of pounds of pull. Place it under a slanted board and roll a dime down the top of board and the dime will almost stop as it passes over it! Whatever you do, do not get it near a TV screen (trust me on this).

[null and void]

Yup. A former co-worker of mine used to stand one on end on the side of a filing cabinet. He called it an engineer trap. Caught a lot of us.

I acquired one from him when I left. My new co-workers stuck it to the inside of the side of my metal desk, it had enough field strength to hold a stapler to the outside of the desk. It looks a little odd to see a stapler stuck to the side of a desk...
