Minimum equipment required: A plastic ice/cooler chest, to serve as a soundproof echo chamber, two (2) cell phones, and an optional digital voice recorder.

Instructions: 1. Call up one of the cell phones, place it in the speaker mode, with the volume turned up, and place it in the chest. 2. Place the optional recorder in the chest, turned on, with the volume turned up.. 3. Close the lid of the chest. 4. Put the other, calling phone, in the speaker mode, with the speaker turned up. .5. Try to communicate with any entities using the calling phone.

Ask them to speak as slowly and as loudly as possible. Keep trying until you are successful!

Note: You do not need a noise source for a sound energy source – voice energy is the source. Listen carefully, and encourage the entities to speak louder, even if no one hears them speaking. You will not have to try to hear the entities over “white noise”. Larger chests, that are square in one dimension and rectangular in the other dimension, will make a better echo chamber. Previously recorded messages do not convince anyone. You must prove it to yourself by doing it yourself!
