To observe how people interact with an object, I placed a bowl of candy out in the middle of a common area. Many of whom walked past the bowl looked at it at least once, some did a double take to read the note written on a card saying "Take one! Have a sweet day!" Everyone seemed suspicious to grab an innocent piece of candy because they didn't know where it came from or why it was out for anyone to take. After two long hours of observing, a group of kids finally grabbed their share.
