Step 7Pick a container
iImage Information

I chose Air Wick Stick Ups because they are the perfect size, come apart easily, unscrew open so the mic can "hear" and are ready to be stuck to just about anything. Behind furniture, under a table or chair...use your imagination. Take the newly modified Mr. Microphone circuit and conceal it in the container. You can use your car FM radio, an MP3 player that has FM and recording ability (great if you want to record the conversation) or any FM radio. Have fun and always use this responsibly.
