Abstract A device for popping corn having a receptacle for receiving popped corn and a popping vessel arranged in the receptacle for receiving kernels of popcorn. A hot air blower charges a stream of hot air downward into the popping vessel and heats kernels of popcorn to a popping temperature. The stream of air drives the popped corn out of the popping vessel and into the receptacle to separate the popped corn from the unpopped kernels of pop corn.
