If you feel you have too much spare time on your hands, you can always kill a couple of minutes by learning how to balance 17 dominoes on one upright domino.
I remember that when I was a kid, my older cousin could somehow balance the entire set of dominos on one. Now that I'm older, I can never remember how he used to do it.
I love at the end, the guy that made the video is so happy with himself, "Unbelievable :) 1 brick keeps 17 bricks. Amazing :D" Redundant. Two compliments for himself and two smilies. Lame.
it's also a standard trick in the discipline of cigar box manipulation. with cigar boxes the whole stack usually gets balanced on the chin. http://www.dube.com/cigarbox/stacking.php
Great comment, me. Yeah, it was awesome.
I tried this with my domino set.. the solid ivory coloured type.. it all came crashing down on the first try...
