A favorite of gardeners for hanging plants and feeding hummingbirds at the same time.  When they head south, tilt the tubes up and use them for bud vases.  Be sure to buy extra glass test tubes and a cleaning brush for your convenience.  Consider adding perches to give your hummers a rest as they fill up with nectar.
