The amazing phenomenon of putting raisins in a glass of champagne.
Pretty attractive right? However, why can they rise and fall so constantly? In fact, this phenomenon depends on the nature of both objects.
As we know, in champagne contains a lot of small carbon dioxide bubbles , they are lighter than water and tend to rise continuously above the surface adjacent to the air. On the other hand, raisins through the drying process were dehydrated, making them wrinkled and shrunk.
When it hits the surface, air bubbles are broken, causing the grape to be pulled backward by gravity.(Illustration).
But when dropping them into a glass of champagne, tiny bubbles will cling to that wrinkled surface, creating enough force to lift them upwards. When it hits the surface, air bubbles are broken, causing the grape to be pulled backward by gravity.
This process keeps repeating until the amount of carbon dioxide gas drops so low that it is not enough to create lift!
