Does the kid still not know anything about physical phenomena and laws? This is a great way to explain to him their features and the principles of operation of electrical appliances. The child will receive basic knowledge in the field of electricity and electronics. This is one of the most effective ways to explain to a little one why a light bulb is on, how the radio works, and to answer more tricky questions in the field of electronics to older ones. Practice is the best basis for understanding the laws of physics, especially since the child comprehends them himself, drawing conclusions from what he sees. In this way, the ability to think logically, observe and experiment is formed. This can also be very useful for mastering other areas of knowledge.

For schoolchildren, science will no longer be an abstract concept, tedious and boring. On the contrary, it will be easier for him to assimilate additional knowledge and “sort it out into sections.” In later life, the ability to work with electronic devices will bring certain benefits, even if the field of professional activity is not directly related to them, so it is worth buying this toy for your child.
