Presto 04820 PopLite Hot Air Corn Popper Plug in Prestos PopLite and the party begins. In less than 2.5 minutes you will have up to 18 cups which is equal to two large bowlfuls of fluffy popcorn with virtually no unpopped kernels. And because the machine uses hot air instead of oil the resulting snack is healthier and lower in calories. Thats not to say you can nott add butter in fact the half cup measuring cup on top of the popper doubles as a butter melter. Simply put in the desired amount of margarine or butter and it melts from the heat produced during the popping process. The clear plastic cover and cup which must stay on during popping so the popped corn does not fly all over the room easily remove for hand cleaning with warm soapy water. No other cleanup is required. While a few unpopped kernels spring out the chute as the machine begins to heats up the chute does a good job of directing the popped corn into a bowl.
