Not true at all. I've done something similar. I took two ring shaped magnets and superglued the repelling poles together using a plastic clamp. After the glue had set, the entire assembly was attractive on all sides, but the space in the center repelled objects inserted there. Bingo. Monopole. No exploding necessary.
No one is going to buy your crappy sh*t. It doesn't matter if you put it in a pop-up, or in a pdf, or in Jenna Jameson's poontang, NO ONE IS GOING TO BUY YOUR CRAPPY SH*T! (ok, I might examine it with tongs if it's in Jenna Jameson's poontang...but that's IT.)
