Even school administrators didn't let the air out of the Arlington High School senior prank Friday.
At least not right away.
Students from the Class of 2012 used 3,300 balloons to fill an entire staircase at the school Friday, and posted a sign saying "No entry, wild balloon habitat," according to an email bulletin from Arlington High School Principal Mary Villano Monday.
When school administrators found the balloon-blocked doors Friday morning, they left the display for an hour so other students and staff could see, Villano said in her newsletter.
“It was quite a spectacle and started the day off with lots of laughs and excitement,” said Villano.
Villano said administrators at the school enjoyed the prank because it was done in good taste and did not have any negative impact on the school day. After an hour, the balloons were popped to clear the stairway for safety purposes, according to the principal’s newsletter.
“I congratulate our senior pranksters who put careful thought into doing something fun that did no harm and did not disrupt the school day,” Villano said.
