Kitchen vent covered.

In the house, there is a kitchen vent at the top of the stove. I didn't realize how big a hole this was to the outside until one day i could feel the cold air near the vent. All this warm air in the house is going right out this hole. I gotta figure a way to cover it up. So i wonder what Macgyver would do.

I went to home depot, bought some insulation, foam seal and self adhesive magnets. Took about 10 minutes to put together. Works like a charm. Easy to put up and remove, while blocking the cold air from coming in.
