There has to be a better way of drying a wet umbrella than just shaking it silly. This Lawn for Rain concept - where you slide a wet umbrella into the styrofoam grass - might be it.
Those green styrofoam faux-grass fingers strain out the umbrella by soaking out the rainwater. What's especially thoughtful of Lawn for Rain is that it'll use that same water to feed the plants at the base. I'm not sure if leftover rainwater is enough for plants to live off of (maybe if you live in Seattle, it could work), but it's certainly a good excuse to have giant styrofoam fake grass in your house.
