The Cambridge Science Festival, a nine day event, is a celebration of science, technology, engineering and math. The festival kicks off on April 24th at the Cambridge Public Library, with a free Science Carnival, where attendees can make blue slime, celebrate the 50th anniversary of the first laser, make ice cream with liquid nitrogen, and many more fascinating exhibits, all of which explore the different aspects of science in a fun and exciting way.

After that the festival continues for the next week with events tailored specifically towards kids, teens and adults that culminates with the Let’s Rock the World Treasure Hunt, an all day geology-based treasure hunt. Participants must find the way using clues hidden throughout Cambridge, each of which leads to the next. Its free to enter and prizes will be awarded to the select few who find all ten clues.
