I've been wanting to invent something like this all my life! Locate items by adding a magnetic sticker to them and then search for it using this device. It tells you how far or close you are to the item! I could save soooo much time owning something like this--as long as I didn't lose the device. :-)
Stick-N-Find Bluetooth Tracking Stickers: The StickNFind works by placing a small Bluetooth sticker onto a remote, pet's collar, or even your child's backpack. You can then use your iPhone or Android device to locate the item, causing it to vibrate and light up.
GENIUS. I think this is a must have for travelling...would save a lot of ziploc bags! Keep the mess in the towel, then throw the towel in the laundry when you get home from your trip.
