Painting with explosives: I always liked this myth
I seem to remember--years back on the Discovery Channel--microchip components being glued together. Now most people use a wavy line of glue on the back of tile--and after years of wear, you can see the hump of the line of adhesive.

So I'm thinking a 3D asterisk shaped charge might do the trick
