My sources tell me that if you put a tireguard over your rear tire, or if you install a bike rack, it greatly reduces the amount of water that gets splashed up.

On a different note, I found the wonderful microwave website (I don't remember if it's been posted, but I couldn't find it). There are still a lot of experiments on here that I'd like to try. I'm not too keen on the soap one though because I don't want all my food to end up tasting like soap.
