Powerful little magnets

Some time ago, I picked up a few 1/4" diameter magnets at Michael's to use as closures for boxes. I finally got around to trying them out on a box with a pivoting lid, and they work really well. I just drilled a hole 1/8" deep for each magnet and glued them into place using a new (to me) glue, Liquid Fusion. It's a clear, non-foaming urethane glue that's supposed to work with metal, and I wanted an easier alternative to epoxy.

So far, so good--the glue was easy to apply and seems to hold well. The magnets are so powerful they hold even without actually touching each other, although I would not use them with objects meant for small children, in the event they come loose. The only thing to be careful about is to put the magnets in correctly, or they will repel instead of attract!
