First you would buy grapes. Next you would let them stay in the sun for about the time you think they are ready. finally, you have raisins
endosmosis
The process in which raisins swell is called rehydration. When raisins are soaked in water, they absorb moisture, causing them to expand and regain some of their original size and texture. This process occurs due to the osmotic movement of water into the dehydrated fruit.
Raisins are typically harvested in late summer to early fall, primarily from August to October, depending on the region and climate. The drying process can take place shortly after harvest, allowing raisins to be available year-round. However, the peak season for fresh grapes, which are used to make raisins, is during the summer months.
osmosis!
raisins will float due there carbonarion and the raisins low density level in them.
Raisins are just dried grapes, so when raisins are kept in water they re-absorb liquid (that they lost in the drying process). They swell to accommodate the new liquid.
Raisins come from grapes. They are made by drying grapes, either in the sun or through an artificial drying process. The drying process concentrates the sugars in the grapes, giving raisins their sweet flavor. Different types of grapes produce different varieties of raisins, such as Thompson Seedless for golden raisins or Zante currants for small, dark raisins.
The drying process worked to preserve them.
When raisins are soaked in water, they absorb the water and swell up, becoming plumper and softer. This process is called rehydration.
the purpose of the dancing raisins project is showing that the carbonation of the soda can float the raisins up in tiny bubbles and make them dance
Raisins are the dried fruit dirivative of certain types of grape, as opposed to currants which come from types of grapes different from those used to make raisins; sorry, I don't know which grape type is which.
the same as they do today with the grapes and stuff
