Temperature decrease in the brain from a Slush Puppie

Matthew PERKINS, Faeeza Lorgat


This paper investigates the temperature decrease of the blood in the brain as a consequence of drinking an entire serving of Slush Puppie (236.6 ml) in one sitting. Due to the limitations of the size of the mouth, the complete consumption was achieved with 3 mouthfuls. The final temperature of the blood in the brain was calculated using heat transfer equations, assuming thermal equilibrium is established, and was found to equal 36.37 ℃, a temperature decrease of 0.63 ℃. In order for significant damage to be done to the brain, more than 3 Slush Puppies must be consumed.
