 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is how to hold the paper cups on a balloon. What you need for this experiment is two paper cups and a balloon and a helpful volunteer. All right, welcome back to Kids Fun Science. Today's experiment is air pressure and so I've got a 12 inch balloon and I've got a couple paper cups and I'm gonna blow up the balloon about just a little bit and then we're gonna put the cups on and then when I blow it up more what it's gonna do is Decrease the air pressure inside the cups and the outside air pressure on the cup should hold it on so let's see There you go Outside pressure stronger so the inside pressure of the cup is lower and when you let go of it Pressure goes back it falls. I hope you enjoyed this experiment if you did remember to click thumbs up and to subscribe Thanks for watching
