If you've ever tried to spray a cleaner — or Lifehacker favourite, a vinegar solution — into the back of a cupboard or up on a ceiling, you'll be aware that spray bottles don't always work well unless they're flat. This neat hack fixes that problem, making your spray bottle work in any direction you choose.
MAKE has the details on the hack, which involves replacing the suction tube of the spray bottle, which is usually quite hard plastic, with a flexible tube weighted at one end. As you move the bottle around, the weight forces the tube to work with gravity, meaning it should always be submerged no matter which way you point it.
