WTF is this?

The game consists of 100 cards. Each of them shows a strange item bought on the internet. One player takes a card and looks at the back (if someone knows what the item is for, they will fill that role). The backside of the cards shows the use and some more information on the item. The other players will now try to find out what the item is for by asking yes/no questions. The player with the card will open that, and can also give certain clues shown on the card. One play consists of trying to guess 5 items; players win if they can identify all of them.
