How do cucumbers turn into pickles i need to know for my science project so please help it's due next week.ty?

Cucumbers become pickles either by fermentation or through acidification. Fermentation will take too long, so acidification will likely be your best bet.

Acidification involves placing the cukes in a seasoned vinegar solution which can be salty or sweet. They also generally include a canning or hot fill process - unless you make refrigerator pickles. Small pickles, spears or slices will attain the flavor you're looking for more quickly. There are many recipes on the internet. See Related links for a sampling.
