 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is pop a balloon inside a balloon. What you need for this experiment is a clear balloon, not white, a black balloon, a pencil, a magnifying glass, and plenty of sunshine. So you take two balloons here. You got a black, nine inch latex balloon and a clear, not a white, 12 inch balloon. Look in the description for the sizes. And then you take the pencil, put it inside the black balloon, and then slowly twist it and bring it out and then pull the pencil all the way out of both of both balloons. And now you're going to blow up just the black balloon about three quarters of the way full. So you can blow that up. Once you get that filled, then you're going to tie the black balloon into a knot. And then once you have that into the knot, you're going to repeat the same process with the clear balloon. Now just blowing up, tuck that black in all the way. And then you're going to blow up the clear balloon about three quarters too, just so the black balloon is can bounce around on the inside a little bit like this. So you blow it up. So now you see I'm tying the clear balloon and then you got the black balloon inside. That's the setup. And now we're going to do the experiment. So now to do the experiment, you take a magnifying glass, it could be any kind. And then you're going to, I hold the clear balloon by the end so it won't pop away. And then you're going to make that little white dot from the magnifying glass zero in so it's the hottest it could be. And it's going to focus in right there for your experiment to work. You got to make sure your hand is still both on the magnifying glass and the balloon and boom, there it goes. No matter how many times I do this, it always scares me because the black balloon will pop and the clear balloon does not. So the science behind us is the power of the sun. Don't blink because you're going to miss this one. Why does the inside black balloon pop before the clear outside balloon with the magnifying glass? Well, the clear balloon has most of the light pass right through it like a window, but the black balloon surface does not reflect any light and absorbs most of it. And the surface absorbing all that light, it absorbs the energy. In this case, the energy is the heat and there's a lot of it. So the heat absorbs into the black balloon and from that focus light sunlight quickly causes the bonds of that balloon to weaken until it no longer can contain the air inside and the pressure from the air just too much and it explodes releasing that air into the clear balloon, as you can see. Look at that. I love how the the reaction that was in slow motion how the white balloon is getting all the the shakes of the top of the inside. So anyway, no matter how many times I did it, I still jump every time that black balloon pops. I hope you enjoyed this experiment.
