Most fun I ever had making popcorn was taking the lid off while popping. My daughter was about 5 or 6 at the time & she had a couple friends over for a sleepover. I said something like "I wonder what will happen if I take the lid off?" and they almost wet their pants laughing as the popcorn was flying everywhere. Yeah, it made a bit of a mess but what a priceless moment with my daughter.
She never asked for a mulligan ....
