Science!

Yesterday my class did science. We made cup phones. We had a question: What is sound? We made the cups and tested round corners and other places. They only work if the string it straight and tight. I learnt that for it to work you need to have the string straight and when you talk you need to have your mouth right against the cup rim and the other person has to have the cup rim right up against there ear.


Do you want to try this experiment?

    We used to do this when we were little. Very cool.
