Install an umbrellascope.
This thin plastic tube comes in 3 lengths which fit together, with appropriately placed mirrors inside. This allows you to see above the umbrella-tarpaulin and thus provides protection against umbrella-related-sight-impairment injuries. Like walking into telegraph poles.
Also provides astronomic benefits of views of the stars, perfect for sheltering under with your honey, on the beach on a drizzly night.
The kit comes with rubber sealant, goggles, view-screen wiper (powered by batteries, and with settings to 'intermittent' and 'continuous') [thanks Waugs], an appropriately themed submarine-captain-uniform of your choice, and a picnic rug for the beach.-- seedy em, Nov 19 2003 A transparent umbrella would be simpler, but with this idea, you could see over the crowd at a parade. (Provided anyone has a parade in the rain)-- half, Nov 19 2003 Would it come with a built-in windshield wiper? It's raining out there, you know.-- Worldgineer, Nov 19 2003 [half] I had the same thoughts about rain and parades, and thanks for not ....ing on mine ;-)-- seedy em, Nov 19 2003 Well, if its THAT kind of parade we're talking about, then count me out-- Letsbuildafort, Nov 19 2003 random, halfbakery
