Drilling tempered Glass?

Well, you could try drilling it...
Seriously, though, if you look at it through polarized sunglasses you can sometimes tell. I don't know if that's always true, though.
edited to add:
da google tells me that tempered glass alters the polarization of light passing through it, so I think you need to be looking through tempered glass with polarized sunglasses AT a polarized light source to see the pattern. Or a polarization filter on both sides of the glass would probably work too...

Use 2 polarized camera filters or sunglasses. Sunglasses make this more difficult due to their tint. Place 1 on each side of the pane then rotate them untill most of the light you're using is blocked. I prefer a cloudless blue sky as my light source. Move the filters/lenes simultaneously across the glass looking for light and dark splotches/patterns. If the glass look uniform its not tempered, if it has the light and dark areas it is.
Try it on the side window of a car first, side and rear windows are tempered and you'll be able to see the effect. I you don't see it there you're probably doing it wrong...

Just a FIY When it is tempered it is heated up very hot than cooled fast. this causes it to make a very hard shell on it. The middle becomes very brittle. Depending how long it is heated and how fast it is cooled depends on how thick the outer shell is. Thoug neverless the middle is still brittle. It forms a melucture structer that when disturbed decentrgrits when disturbed. The outer shell can be drilled or cut BUT as soon as the middle it touched(disturbed by drilling hitting or scratch)) POW it will blow. just like in the youtube listed above.
