HoseSplitter
Hose splitters can feed two hoses from one hose or spigot. Sadly, some have tiny little plastic valve knobs which are difficult to turn. Fortunately, these knobs can be extended with longer handles, which can be made from the (bent) wire handles of an ACCO binder clip, bent washers, and a longer attachment screw.
