Duffus came home one afternoon to find his wife in the kitchen making homemade jam. She had a few jars on the table, and was attempting to tape the vacuum hose on a lid, when Duffus arrived. "What are you doing, dear?" he asked, confused by the piles of twisted tape that clung to everything in the kitchen. Mrs. Redneck says that vacuum sealing the jars helps keep them fresher and tasting good longer. Duffus laughed as he put a large pot on the stove to heat up, then filled up the sink with water, took the vacuum and tape from his wife and said, "Let me show you how it's done, dear."
How was Duffus planning to vacuum seal the jars?
