Liquid nitrogen was used to destroy the gourd and was part of the Great Pumpkin Smash event at the North Shore attraction. Visitors were invited to throw their Halloween pumpkins off the roof and were also treated to a science demonstration on pressure and temperature change which resulted in the exploding fruit/vegetable. In 1893, the United States Supreme Court ruled on the question of whether the pumpkin is a fruit or a vegetable, and ruled that plants consumed as part of the main course shall be considered a vegetable, while plants consumed as appetizers, desserts, or out of hand shall be considered fruits. So, botanically speaking, a pumpkin is a fruit, however, under tariff regulations many countries classify the pumpkin as a vegetable.
