Instructions
Decide who best fits in your spy club. Pick people you know are trustworthy. Friends you have had for years are going to be your best candidates.
Create a name for your club. Try to make it something that is a word puzzle that might confuse others but has a special meaning, like "Intel G Quad" with a meaning of "Four inteli-gents" or "four intelligent boys."
Pick a secret location for your club house. Using a difficult-to-get-to tree house would be an excellent location for your headquarters, especially if the entrance can be hidden. Other ideas include a bedroom with "Keep Out" signs or another hidden space.
Purchase or make some top secret spy gadgets. A pair of binoculars, tape recorder, cell phone with a camera or a watch with a timer on it all make for great gadgets for your spy club.
Start a spy mission. Find out who has been stealing the neighbors newspaper by setting up surveillance. Organize your room in such a way that you can tell if someone has been in it messing with your stuff. Snap a secret picture of a bully as he is causing problems so you can report it.
