The common idiom is usually squeezing blood from a stone but that would be kinda icky. Not very useful too unless you have vampiric plants. The Kikkerland “Water From a Stone” on the other hand is a gadget that slowly releases water into your planter over the course of 3 to 4 days. No squeezing required either.
Perfect for making sure that your plants get watered while you are away for a few days, the automatic self-watering device holds 7 ounces of water. Also works pretty well for lazy or forgetful gardeners.
The Water From a Stone globe is made from hand-blown glass and it comes in a set of two.
