Hi Redstreak,
I use a thumb tip with small magnet. Use it to balance two coins edgewise on top of each other, then crosswise. For the coup de grace, hold one coin below the other edgewise then let it hang...as the jaws drop in amazement..just give it a blow and set it spinning. Woweeeeee!!!

note: I use two english 2 pence pieces, as they have a high nickel content and hence the magnetic field passes through them.

How far away from CD/DVD players do you have to be. I wouldn't want to ruin my electronics for a magic trick....also in a car, would it affect you radio?

I might be stating the obvious here, but apart from elecronic devices, watch out for magnetic data storage, i.e. video/audio tape, floppy disks, credit/ATM cards, etc.
Also watch out for metal detectors (magnetometers). I walked into a bank with a small neodynium magnet on me, and the guard wanted to know if I had a firearm...

What is shimming?

Does anyone know where I can get just the PK magnet in the Pro PK Kit alone instead of the whole kit? Also, with this PK magnet, how far do you have to be away from a magnetic object in order to move it?

I picked up #5 a few weeks ago and am happy with it so few. It is pretty strong, but not as strong as the M5 from what I have been told.
