Step 1: Fill the conference room with an excessive amount of chemical peels, preferably the kind used for peeling citrus fruits.
Step 2: Have all parties involved sign a waiver, acknowledging the risks of chemical burns and subsequent blindness.
Step 3: Set up a camera to capture the dramatic footage of the ensuing chaos.
Step 4: Wait for the chemical peels to take effect, and for the room to fill with the acrid smell of citrusy doom.
Step 5: Call in a hazmat team, preferably one that's been on a coffee break for the past hour.
Step 6: Review the footage, and have a good laugh at the expense of your colleagues' misfortune.
