Mechanical toy - “Tumbling Bear”
This toy differs from factory mechanical toys in that it does not require a plant or a battery, since it moves according to the laws of physics - the conversion of potential energy into kinetic energy. The main part of the tumbling bear is an internal mechanism that provides movement - a hollow tube with a ball rolling inside. The tube can be made independently of cardboard of arbitrary size, and you can use the finished one - the inside of a roll of toilet paper. The ball can also be taken either ready, but in the absence of one, you can make it yourself.A small piece of clay with metal objects that are not needed in the household is easy to turn in a heavy balloon,hiding details (nuts or bolts) in a plasticine shell.
