Room 4000 is at the far end of the hall on the fourth floor. Set out your snacks and drinks on the tables in the back of the room. After the talk, collect aluminum cans for recycling and clear trash from tables. Return supplies and empty cans to Selker's lab. Dump ice water from coolers, and set down with lids ajar so they will dry inside.
Leftover pop can remain in the cooler.
Dump airpots and rinse with fresh water. Take home or give away any leftover fresh food and drink items.
