Rain Sensitive Umbrella

"It's stopped raining, you can put it away now"

This umbrella is coated with a water sensitive membrane. Once it has stopped raining, the sensors transmit a signal which powers a green led on the inside of the umbrella.

Once the user sees the green light, they know they can safely put their umbrella away.

It would seem that there is a market for this, as I've just seen several people walking along underneath umbrellas, even though it stopped raining 5 minutes ago.

       Completely stupid - I like it [+]

       I pictured an umbrella with a voice thingy telling the user things like, "Oh, yech! I hate the rain.", "Hey, I'm getting all wet over here!", or "I'm melting, I'm melting. Please make it stop.",or "Hey little rain drop, Iknow you had a long trip. You just rest on my top for awhile, be cool, little dude."   

       I guess your idea is more useful. Could we have it do both?

       [ntss] The umbrella in the description is from the economy range. The "Rainmaster" incorporates all the features you mention, and a few more...

       maybe you could also have it download the local forecast and blink a little red light so you don't forget it when you leave the house...

       [rascal] Ah, so it's the "Rainmaster" you'd be wanting then...

       Proximity sensors alert you that you're about to bump into someone else's umbrella.

       these brollies just close down on your head without warning?

       The light thing i was talking about is apparently in the works already. It looks pretty cool.
