Today is my last day of school at my high school, and thusly I shall be engaging in a senior prank.
I had plans of one earlier this year involving replacing the powerpoint slides that are displayed on our school tvs, but I discovered from observation that the room with the computer has an alarm (set off many times this year).
A friend of mine just concocted a scheme involving green food coloring, dry ice, and other miscellanious items. We've already got 4 people in on the plan and hope it goes well. I'll follow up on this after I get home.
