The purpose of this experiment was to determine which brand of popcorn, Orville Redenbacher, Newman's Own, Best Yet, and Jolly Time, pops the highest percentage of kernels out of 100. To do this, 100 kernels of popcorn were popped, and the number of popped and unpopped kernels were compared. This was done four times and then an average of the total of popped and unpopped kernels was found. It was found, contrary to the stated hypothesis, that Best Yet has the highest percentage of popped kernels out of 100, popping 87% of its kernels. Not far behind was Jolly Time which popped 84.2% of its kernels. Less than two percent away from that was Orville Redenbacher which popped 82.5% of its kernels. Last was Newman's Own which popped only 78% of its kernels.
