  They do seem to move up and down, yes. Bubbles of carbon dioxide gas seem to carry the raisins to the surface, then pop, and the raisin sinks again 😮

  Yup! They will bounce around as the bubbles rise to the top but will eventually settle once the gas is gone out of the drink. I wouldn’t recommend putting them in anyone’s drink…I don’t think little shriveled brown blobs make a good garnish for any drink 😉
