The wealthy collector can track down a bit of this ultra-rare and synthetic element for his or her collection but the rest of us can either put up with an ugly and prominent hole right in the middle of the periodic table or make do with a dummy like this one. As far as dummies go though this is an attractive offering showing what technetium actually looks like. In a military lab somewhere. Just the size of that thing in the photo is probably enough to make a Geiger counter go nuts!
