[الناسكة المتعبدة]

1- through this experiment we will try to explain how to talk to someone through two cans of yogurt, tape thread or wool, and matchstick, without rising your voice or bothering others.


2- first of all we took two empty yogurt cans, and made a small hole in the bottom of both of them, then we linked the thread with matchstick and put them in the hole we made, person A has to be far from person B and the thread should be stretched so the sound can pass and be clear.
