Physics students celebrated Halloween and proved gravity still works by pushing pumpkins off a roof at Boston University. There were 36 pumpkins in all and some of them were filled with whipped cream, neon paint and flour. There was even one frozen in liquid nitrogen. The tenth annual pumpkin drop was in honor of a centuries old experiment.
Carl Ludwig Chair, Physics Dept., Boston University It builds on an experiment done by Galileo in the 1600s where he dropped objects of different sizes off the leaning tower of Pisa and saw that it didn't matter how much they weighed, they all fell at the same rate and so we follow that up by dropping pumpkins off the top of the Metcalf Science Building here at Boston University.
Dropped from about 60 feet, the students saved the best for last. A 144 pound or 65 kilogram pumpkin went off the roof for the grand finale.
Ludwig said he hoped the event inspired both children and students to consider science careers.
