 Today I'm going to walk you through a demo of the Bubbles on Bottle experiment that is part of our weather wow Up in the air virtual field trip as well as the activity on our modeling the behavior of air with bottles on the Ucar Center for Science Education website We invite you to do this experiment at home in a classroom with any group To explore the effect that temperature has on our air So we're gonna hop over to our experiment now so you can see what you need to do it You basically need two bins or containers Containing a few inches of water one container should have hot water This is freshly heated up in an electric kettle. You can do a microwave hot water dispenser Whatever you have at your disposal, but nice fresh hot water and over here. We have cold water It's great if you still have the ice cubes in there You want a big temperature differential here the other piece that you need is a bottle and The best bottles it could be soda bottles juice bottles Any bottle that you have at your disposal ideally if it's clear that'll allow you to see what's happening on the inside And you want it to be able to fit into your containers of hot and cold water And you want the opening to fit into the last ingredient of our experiment, which is dish soap so there's just some average Run-of-the-mill dish soap you can find in your kitchen that is been diluted a little bit so diluted dish soap And we've also seen some groups have success with this using a juice bottle in a plastic cup with some hot and cold water Again, we have hot water So make sure that you have some grown-up supervision if you have younger students doing this So our bottle to do the experiment what we're going to do is we're going to dip our bottle into our dish soap So that we have a nice film covering it and Then we are going to take that bottle put it in our hot water And you're going to see oops and if it pops that's okay. Just start it over again So you should see a bubble form on the top come up and then we switch it over as part of the experiment down into the cold water and Our bubble goes away It is not popped. It is still in here It is actually fallen down here and if you have colder water that will speed up the process of it moving downwards and Also go down further So I recommend having some ice cubes in your water But you can even if your film is still there if your bubbles in the bottle you can move it back to the hot water and Watch your bubble Reform so that is the basics of the bubbles on bottle experiment We hope that you have fun exploring and experimenting with it If you want a full step-by-step guide with inquiry questions and steps to walk through with a group You can check out the guide on our website at the U-Car Center for Science Education You can also book a free virtual field trip live with one of our educators Look for whether wow up in the air virtual field trip on our website as well for that But in the meantime keep exploring and have fun
