Here's an easy one. It's 100% mathematical, no trickery involved.
There is a lake in Alaska. Every Winter, beautiful ice lillies begin to form on the lake.
With the ice lillies, come the ice lilly pads. On the first day of Winter every year, one ice lilly pad grows. The number of lilly pads doubles every day until the entire lake is covered with ice lilly pads on the very last day of Winter.
On what day of Winter is the Alaskan lake exactly half full of ice lillies?
PM me the answer. The first 5 people to get it right will win... exactly nothing.
