Dancing Raisins

Materials Required
  • A transparent glass jar.
  • Carbonated water(soda).
  • Raisins(dried grapes)

How to do it

  • Pour the carbonated water or soda into the glass jar.
  • Drop few raisins(dried grapes) into the glass jar.
  • Ask the kids to observe what happens. The raising start dancing.
  • This is because, bubbles of carbon dioxide gas in the liquid are much less dense than the liquid or the raisins.
  • Raisins are denser than the liquid and the carbondioxide, so they will sink.
  • Carbondioxide bubbles gets attached to the wrinkles on the raisins.
  • When the raisins are attached with the bubbles they become less denser than the liquid, so they start to rise to the top again.
  • The carbondioxide gas bubbles starts bursting and then the raisins become denser than the drink, so they sink again.
  • This looks like the raisins are dancing in the liquid.

What is learnt

  • The property of density of the substance.
