 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is the rubber chicken bone. As always, adult supervision is required. What you need for this experiment is vinegar, a chicken bone, a cup, or a jar. So for the setup, you're going to take your chicken bone and let it dry out for a couple of days before you do this experiment. So you don't want to just get your chicken bone and start off. You can hear it's kind of hard there and then to prepare it for the experiment, you're going to fill up the jar or the cup. A jar you just have a lid so it'd be more where it's not going to tip over. But if you have a good spot, you can put it in a cupboard or somewhere, let it sit for seven days. And then when it comes out and done, make sure you completely dry it off because it's going to squeeze out extra vinegar if you don't completely dry it out. So the science behind this experiment is vinegar is considered an acid, right? So it's a mild acid, but it's strong enough to dissolve away calcium, which is in the bone. So that's why you need seven days because it takes a little while to do that. But once the calcium is dissolved, there's nothing to keep the bone hard. So there's left is just a soft tissue. Now you know why your mom's always trying to get you to drink milk. It's the calcium in the milk that goes into your bones that makes your bone stronger. That's why you're nice and strong and they can't bend. Also remember, don't take a vinegar bath for multiple days. So just to show you how soft the bone is, I'm just taking a regular steak knife and I'm very easily can cut right through the bone. You can still see the inner side of the bone, but it's nice and flexible and it bends. So I hope you enjoyed this video. If you did, remember to click thumbs up and to subscribe. Thanks for watching.
