post-it notes, and stick that on top of the stack on the mirror.
The only pen in the house is tied to the phone by the front door,
a long way from the smallest room. Being a good host, there is
a wide selection of very tempting drinks and snacks in the lounge.
By the end of the party, all 100 post-it notes have found their
way onto the stack on the mirror, as instructed.
What's the smallest number that can be written on the top-most
I'm thinking that we can get as low as two (assuming we start
primed at zero).
Imagine if everyone goes to the room in turn and heads off to write
"one". Person A puts their "one" on and then comes back after B, C,
D, etc each put their "one" on, reseting her number to "two" each time.
However, right before her last trip to the bathroom she does tequila
shots for five hours and B-J make all of their trips before she returns,
putting her "two" at the top of the pile.
We have a winner. All that matters is that someone reads a 0 in order
to later place the 1 which resets the final poster into making 2 his
