Now, it's time to mount the counterweights (the 4 of the 5 batteries). Simply glue them on with one of my favorite weapons: The Hot Glue Gun.

Hmm...what about lead shot? I went to down to the gun store and bought a 5 lb bag of 00 buck for pretty cheap; I mix it with a little white glue; once the glue is dry it does a pretty good job of holding the shot in place. Lead fishing weights hammered flad and hot-glued on would probably work well, too. Just be careful; that stuff is kinda toxic. The batteries are a cool idea, though - especially if they're dead and are being given a second life as ballast.

no, offence, but glueing BATTERIES on is a bit dodgy. I think that you could just put more CD's around the base
