The materials that we are going to use are an egg, a bowl, a balloon, a small plastic bottle and vinegar. 00:00:00
The first thing we have to do is crack the egg and stay with the shell. 00:00:12
Once we have the shell, we are making pieces and put it in the bottle. 00:00:18
The next step is to pour a little vinegar into the bottle until it completely covers the egg shell. 00:00:23
And finally, we put the balloon in the mouse piece, remove salinity and weight. 00:00:30
After a few minutes, we will see how the balloon has gradually been inflated. 00:00:38
What has happened here has been a chemical reaction. 00:00:45
The shell of the egg has calcium carbide, which, when reacted with the acetic acid of the vinegar, releases a gas called carbon dioxide. 00:00:48
This gas has expanded and has sued space below the portal, so the pressure has started to cause the balloon to inflate. 00:00:57
And this has been our experiment of the magic balloon. Thank you. 00:01:06
