Here’s a really interesting looking gravity soda holder. It has the awesome ability to strike up quick conversations at the table, having both the soda bottle and the holder made of a simple piece of wood looking as if they are defying gravity.

This isn’t magic but simply science at work, with the center of gravity of the two objects lowered to the narrow edge of the wooden holder. It makes it so stable in its pseudo-instable state such that it can even stay upright on a narrow ledge! Absolutely cool stuff there.
