> Please somebody explain what pickels is?

Spelling is pickle.  Food; usually side dish.  Cucumber
pickled in brine (salt water) & spices [I think] to give
varieties such as dill pickles, sweet pickles, etc.
Served whole, sliced, chopped into relish, etc.

Whole pickles are used for the glowing food experiment.
