California tumbles into the sea

It's the end of the school year and many students are anxious to finish the few days we have left. Many if not all the seniors have stopped coming to school all together. However today seemed to be very strange, there were some familiar upperclassmen faces today. This was very odd because many of the seniors vowed not to come back after they finished exams. Which mean't they were here for only one reason, to perform their senior prank. Skipping ahead in the day to the last class, I find my self trying to figure out their prank. That's when I smell a weird but ver recognizable scent. The scent of a ball gel that we only saw in commercials. The bell rings, followed with a loud boom. Next thing i know purple little balls rolling and kids falling to the ground. The seniors are laughing and recoding as they watch their orbeez mess.
