BRIGHT SPARK THE LIFT A lift is on the ground floor. There are four people in the lift including me. When the lift reaches first, floor, one person gets out and three people get in. The lift goes up to the second floor, 2 people get out 6 people get in. It then goes to the next floor up, no-one gets out but 12 people get in. Halfway to the next floor up the lift cable snaps, it crashes to the floor. Everyone else dies in the lift. How did I survive? Two half-full barrels are dumped into one of the empty barrels. Two more half-full barrels are dumped into another one of the empty barrels. This results in nine full barrels, three half-full barrels, and nine empty barrels. Each son gets three full barrels, one half-full barrel, and three empty barrels. AUGUST SOLUTION
