Have you figured out how to get the tops and bottoms off the cans? I've tried hole drills & cutters, but the sides of the cans are so weak that the drill just grabs and twists them out of shape - if it doesn't send the can flying.

With the bubble wrap, I've made wooden frames that just slide into the window openings. A bit of foam around the outside edges makes a tight seal.
