 Hello everybody, joining us today for our NCAR Super Science Saturday event. We have kicked off the morning with a dance party, some rocket launches, and we have so many more fun things coming up throughout the day. Right now, for this hour, we're going to have a little throwback to last year's virtual Super Science Saturday event with one of our favorite experiments. And so this is a really simple experiment that you can do at home with just a few materials. What you're going to need to gather if you want to do this experiment is some vinegar and some baking soda and a sealable plastic bag, like a Ziploc bag. And as you'll see in the picture, some paper towels in case there's a little bit of a mess. So we're going to put a hold on this experiment for 10 minutes in case any of you need to go run around the house and dig up some supplies so that you can do this. And then when we get back in 10 minutes, we're going to show you a video recording where our friend Cecile is going to walk you through this experiment. Now this is a DIY, a do-it-yourself experiment. So we're going to play the video and she's going to walk you through how to do it and what you're going to discover from that. And then you're going to have a little bit of time in the rest of the session to just play around, try it again, and or clean up your experiment and get ready for our next session at 10.30. So we're going to leave this picture up for a little while, give you a chance to go gather your materials, and then the video for the experiment will start in exactly 8 minutes and 19 seconds. Thanks everybody. I'm going to show you an experiment that you can easily do at home, that you just need baking soda and vinegar. Here I'm taking apple cider vinegar because it has a color and I like it, but you can use any type of vinegar. And I'm taking a paper towel, and I'm going to put 3 tablespoons of baking soda, 3 tablespoons to a set one. And then I'm closing, I'm doing a little wrap here with the baking soda inside the paper towel. Then you see I have a little wrap here. Now I'm taking a zip lock bag, and then I'm going to put half a cup of vinegar, the baking soda, and I'm putting it in the bag, and I'm going to close very carefully the bag, but I'm holding the baking soda at the top, that it's not falling in the vinegar yet. And it's very important that you close very well the bag. It should be very well closed. Then there's nothing that can get in or out. Okay? Okay, then my bag is only well closed, and now I'm dropping and I'm shaking. And then what you see, you have a lot of bubble coming and the bag is becoming bigger. And this is basically CO2 that's escaping, and you see the bag, there is a lot of pressure building inside the bag. Then you see you have the bag explode with the pressure of the CO2 inside. Then it's a fun experiment to do at home. Then I recommend that you do this in the garden because you can make a mess inside. I hope you enjoy it, and thanks for watching.
