Not funny

I know none of our speech and debate kids weren't involved...but if you have information as to who is setting off the smoke bombs in the building today...please share ASAP. The second one wasn't funny with at least one student throwing up and two suffering from asthma attacks. Given all the has happened in the past two days, I don't think I would want to be involved in this stuff. If it is a senior prank, it isn't funny.
