Perfect for catching roadrunners.

Well, the Wikablog project is ticking along nicely — 269 blogs registered so far, and more every day — and it's already got so diverse that it's pretty damn interesting. Today, I found Inkycircus, which appears to be rather excellent:

we are three science journalists, living in london and trying to start a magazine. a science magazine for women. mostly. it is hard and sometimes makes us want to cry. so we made this.

A science magazine for women is A Good Idea. I'd buy it. And I'm a man.

Yesterday, they posted a link to United Nuclear, who are selling stupidly powerful magnets:

The magnets listed below are very powerful, much more powerful then magnets most people have seen, and need to be handled with proper care. The magnetic fields from these magnets can affect each other from more than 12 inches away. Please note that these magnets are fragile. Even though they are coated with a tough protective nickel plating, do not allow them to snap together with their full force or they may chip, break, and possibly send small pieces of metal flying on impact. Our larger magnets can easily bruise fingers and even break finger bones as they attempt to connect together. ... If you or someone in your household has a PACEMAKER or another electronic surgical implant, don't even think of ordering these items.

That's just the little tiny ones — smaller than a coin. They also have Supermagnets:

If you really need unbelievably powerful magnets, here they are. Uses include magnetic steering of nuclear particles in homemade accelerators, levitation devices, magnetic beam amplifiers, scrap iron separators, etc.

Beware — you must think ahead when moving these magnets.
If carrying one into another room, carefully plan the route you will be taking. Computers & monitors will be affected in an entire room. Loose metallic objects and other magnets may become airborne and fly considerable distances — and at great speed — to attach themselves to this magnet. If you get caught in between the two, you can get injured.

Two of these magnets close together can create an almost unbelievable magnetic field that can be very dangerous. Of all the unique items we offer for sale, we consider these two items the most dangerous of all. Our normal packing & shipping personnel refuse to package these magnets — our engineers have to do it. This is no joke and we cannot stress it strongly enough — that you must be extremely careful — and know what you're doing with these magnets. Take Note: Two of the 3" x 1" disc magnets can very easily break your arm if they get out of control.

....

We can only ship these magnets by ground UPS — they cannot be shipped via air as it will interfere with the aircraft's navigational equipment.

United Nuclear have missed a great marketing opportunity by not calling themselves "Acme".
