SOUND THE ALARM

Available in six bright colors, this nifty palm-sized booby trap wails loudly when it gets jostled, simultaneously sending a message to your smartphone ($44 at BleepBleeps.com). Named Sammy Screamer, it is a handy parenting tool — snap it onto a treat drawer or dangle it from the door of your home office to prevent hiding-and-seeking interlopers. Or secret one onto the frame of your fancy bike — it can serve as a hidden alarm while you duck into a café.
