# Interesting things to do around campus

So you haven't had one of these articles for four weeks. some of you may be going into withdrawal, and some of you may have taken up dangerous hobbies for excitement. Others may not care, but that's life. Anyways, here's your fix.

• Build sand castles in the bins of sand they have around to spread on the paths.
• Burrs stick to geese. Use this knowledge and a slingshot to attempt to velcro two geese together. If they haven't migrated by now, they're probably stupid enough for it to work. If you can't find any geese, ducks may work as well.
• Walk into a random exam and write it.
• Try to start a rave party by bringing a boombox and a strobe light into lecture halls.
• This week's different sounding floor tiles are actually in MC! Sixth floor, just outside the southeast stairwell, inside the circle on the floor. Remember to take a ball of yarn, a GPS, several maps, and a guide so you don't get lost. Supplies of water and food to last approximately a week are also advised. You won't have to go far into the sixth floor, but strange things happen up there.
• Decorate the wall by the stairwell in Env 1. It's large, it's blank, and it has lights pointing at it. All it needs now is people to write things on it. Things like proofs of the mean value theorem, or the code for quicksort, written in assembler.
• Figure out the minimum number of tunnels or bridges that would need to be constructed to allow the entire campus to be connected via indoor routes. Graph theory is your friend here.
• Figure out which of this week's interesting things to do has been used in a previous mathNEWS issue
• Convince someone else to do any one of the listed activities. Bonus points if it's one of your professors.
• Spread salt onto cafeteria tables in a line, then leave a straw next to it.
