 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is the Karate Chop with air pressure. As always adult supervision is required. What you need for this experiment is some newspaper and a ruler. If your ruler has a metal strip along the outside edge, make sure you remove that metal strip as this experiment will not work with that in it. Today's experiment is going to be about air pressure. So we have a ruler and we're gonna have newspaper and you get these at the dollar store for four for a dollar. Make sure it doesn't have that metal strip in here so just take that out. If you put it here we know there's 14.7 pounds of pressure all the time pushing down on this but there's not enough surface here so when we hit it it's just gonna flop. So if we put the newspaper here and then put the rule underneath it now we have a whole bunch more surface area holding down that 6,920 pounds of pressure. So when we do like the Karate Kid and we get in here and we go one, two, three. It breaks like that and there we go. So all this air pressure holding this down in the corners makes it very easy where it can't push up and it breaks it. Hope you enjoyed your video remember to click thumbs up and to subscribe.
