Rapture, be pure

I'm looking for a class that teaches how to use plastic wrap to keep food fresh. I've tried Saran Wrap, Glad Wrap, and various other kinds of "cling wrap" but they stick together too much.

I pull about a square foot of plastic off the roll and it already folds on itself at the edges. I rip the wrap along the cutting edge and it stretches out, then breaks free and implodes into a shiny crinkly ball which is not helpful.

Using more plastic just makes it worse; it sticks to the length of my arm and the cats walk into the kitchen to get a good vantage point in the event that I accidentally suffocate myself.

If anyone can direct me to a class that meets nights or weekends, I'd be happy to take it (pass/fail).
