When I was in upper secondary school, I was in a perpetual coma during physics. I just didn't get it. Inertia, momentum, potential energy and all those complicated formulas were lost upon me. I hated physics.
Last year I made Barbecue Sauce and stashed quite a bit in the freezer. The containers were taking up space. Besides, I did not want to freeze the sauce for too long because that might affect the quality.
