Tests on non-standard thinking
The tasks that are offered to you this time are characterized by a weakly formalized condition. So, if you like to talk in the face of uncertainty, welcome under cat.
Task 1.

Task 6.
The dam lacks one brick. Through the resulting gap the size of 5 cm X 20 cm water flows. The Dutchman who discovered the leak has a saw and a cylindrical wooden pole with a diameter of 50 mm. What is the best way for him to cut a pole in order to plug the gap?
Task 7.
The bottom of the wine bottle has the shape of a cylinder. Its height is 3/4 the height of the bottle. The upper quarter of the bottle, consisting of a neck and a smooth transition to the bottom, has an irregular shape. In the bottle until the middle of it is poured liquid.
