cycle 2 week 4 ( The Screaming Quarter )

This video was about making a quarter scream. What they was tellimg me how to make a quarter scream. First you hva to get dry ice that does not melt at all. They was saying how if you leav and come back in a hour the dry ice will not melt but it will get smaller and that is called a sumplenment. Now if you put a qaurter on dry ice the gas would want to expand and the qaurter will vibrate. That is what make the qaurter scream which is he solid and gas. What i learned from this video is that gas and a solid can make a qaurter scream. But not just any qaurter it can do the same for metails to. I also learned that dry ice does not melt or make a pile of water it just get smaller without melting. That is was The Screaming Quarter Is About.
