It's sunny and sunny today, and I have nothing to do at home. This reminds me that I made an interesting little work last Wednesday-dancing tires. Why not do it again? Maybe, in a few decades, it will be exhibited abroad!

I first took out a motor and a tire from the toy box, then a wire at both ends from the repair box, and finally a rechargeable battery from the battery box. After the preparations are ready, you can start.

First of all, I aim the hole in the tire at the place where the motor has a small iron bar and insert it, which becomes a part of the dancing tire. Then aim the two wires at the place where the motor has metal pieces, insert them and tie a knot, which becomes the basic part of the dancing tire. Finally, aim the battery at the other end of the two wires, press it, and the small tire next to the motor will turn. Then put the little tire on the table, and the little tire will jump around on the table, as if dancing, which is very beautiful. Its principle is: the battery sends current to the motor through the wire, and the motor will rotate, driving the tire, so the tire will rotate. Cars, electronic watches and electric fans in our daily life are all made according to this principle.

Making small productions can not only cultivate our hands-on ability, but also cultivate our brain ability and help us understand the common sense of daily life, so I will do more small productions in the future.
