Cool Gadgets for Girls: Shower Genius Waterproof Notepad

Cost: $15 at ThinkGeek.com

The gimmick: The next time you're in the shower and suddenly have a brilliant idea, recall a forgotten phone number or figure out the lyrics to "Our Lips Are Sealed," you'll be able to immediately write it down without the words getting warped or washed out.

What the experts say: "The Shower Genius Waterproof Notepad is easy to mount on the walls of your shower," writes Softpedia, "using its double-sided sticky foam layer or the keyhole slot." And Coolest Gadgets says that with this pad you'll "never forget one of your ideas again."

Upside: The set not only comes with the convenient mount, but three refill pads and a pencil stored in the top. You can use any standard writing pen or pencil on the pads.

Downside: The waterproof paper refills are $6.99 per pad.
