Cracking the ice on LEDs.

This is a technique called cracking the ice where an standard lensed LED has the end of its resin case cracked off with a pair of cable cutters. (snips, side cutters, wire cutters)
The resultant cracked ice effect on the end makes the light fragment out in random directions making the LED look a lot brighter from all viewing angles.
Note that care must be taken not to crack the resin down to the area of the chip itself or the tiny wire that jumps from the side terminal onto it. Also note that the end of the LED flies off at high velocity and ricochets around the room with a peeeeow noise, so make sure anyone else in the room is adequately shielded or has eye protection.
