If you have a glass-top table witha beveled edge before the edge of the glass, you can shine the laser into the glass perpendicular to the beveled plane (or make adjustments) and you can see the laser bouncing back and forth inside the glass. I guess this is because at the angle the laser enters the glass, it transmits, but then when the laser gets reflected off the parallel sides, the angle is more acute and reflects.
