The Cave of Treasures
Can you help the adventurers find their way to the treasure?
SOLUTION
The solution is shown below.
The Frozen Lake
You wake up on a frozen lake in an isolated region, a hundred meters away from the shore. The surface of the lake is frictionless, and no grip of any kind can be attained over it. You find just your mobile phone in your pocket, but when you take it out to call for help, you realize there is no reception.
If there is no wind force to help you escape, what are you going to do to avoid freezing to death?
SOLUTION
Throw your phone as hard as you can. Thanks to Newton’s third law of motion and the frictionless lake, you will start sliding away.

On Fire
Slylock Fox and Max Mouse needed the rope on the ground to escape, but none of the onlookers could throw it as high as their window. However, Slylock and his sidekick found a solution and managed to escape the fire. What did they do?
SOLUTION
Slylock asked the fisherman to cast his line to their window. After the fishing line was in Slylock’s hands, he told the beaver to remove the remaining line from the reel and tie it to the end of the rope. Slylock used the line to pull the rope up and then went down along it.

10 Dots, 10 Coins
If you have 10 dots on the ground, can you always cover them with 10 pennies without the coins overlapping?
SOLUTION
Assume the dots lie in a plane and the radius of a penny is 1. Make an infinite grid of circles with radii 1, as shown on the picture, and place it randomly in the plane.
If we choose any point in the plane, the probability that it will end up inside some circle of the grid is equal to S(C)/S(H), where S(C) is the area of a coin and S(H) is the area of a regular hexagon circumscribed around it.
