Today, we made a cup-A-Phone. It is an old communication tool. It is using a cup and a string. Then the string brings the sound wave to the other cup. So we have a try at the Atrium. It waorks. My parthner is Gian.
It was break time. I and Gian played with the cup-A-phone again. The second try Gian was on the 4th floor and I’m the 2nd floor. Gian dropped the cup-A-phone so I can get it
I was a thinker because I solve how the cup-A-phone works. I was a communication because I hear what Gian is saying and Gian listen to me.
I learn that sound not always using electricity it can without electricity.
