There's an old trick performed at the dinner table demonstrating the principle of center of gravity: Make the claim that you can balance a quarter (or other thick coin) on the rim of a drinking glass. Most people will bet it can't be done. Then take two forks placed end to end (tines overlapping) with the coin jammed between the tines -- this makes a rigid assembly with the fork handles hanging down from the coin (wish I could draw a diagram!). Now you can easily balance the coin -- forks attached and hanging down lower than the coin -- on the rim of the glass. The principle is that the center of gravity of the system is located BELOW the coin due to the weight of the fork handles -- easily allowing it to balance stably & even resist gentle tapping or spinning. Hope this is the kind of answer you wanted. p.s.: Don't eat with those forks -- coins are full of bad germs!
