The product consists of 12 wooden cylinders and a wooden base in which they are placed. Each cylinder has a small handle at the top, which under pressure exerts resistance. The cylinder is divided into two groups with a white and black handle.
These handles have a different resistance from 500 to 1750 grams. Cylinders in both groups are equivalent, i.e. the resistance of each cylinder with a black handle corresponds to the same value as a cylinder with a white handle. When working with these cylinders, children realize that despite the same form of objects, they must apply different strength to push the handle. In addition, activities with this product develop the motor skills of the hands and fingers.
Game dimensions: 30 x 10 x 10 cm, weight: 750 g.
The activities with this product are suitable for children over 3 years of age.
