Dancing Raisin

Try this at home

Drop a raisin (sultana) in to a glass of soda water or Champagne, and see it dancing.

No it is not that you could be drunk at that time. This is due to the carbon dioxide (CO2) bubbles in the liquid stick to the raisin and creates enough volume for it to push it up. And when it reaches to the top, and CO2 bubbles escapes out it makes it dense and push it down to the bottom. This continues until there are enough CO2 in the liquid, and there are enough of those in Champagne or soda water.

By the way, Champagne is the name of a region in France but most popularly is a sparkling wine produced from grapes grown in the Champagne region of France.
