This trick could come in handy at a party where someone might knock it over, but it has its uses in everyday life as well. I might use this at my computer desk or when playing video games so my drink won't get upended by any wires, and it could also save you from a big headache at your workbench, where an erratic swing of a hammer could send it flying.
