What is the simplest handmade? To be different from others, the simpler the better, hurry up...

The simplest: make a pencil case! Do you have any unused glasses at home? Or drop the teacup or something, try it, as long as it is heavy enough to hold the pen. Find a beautiful piece of cloth or colored paper to make a piece of clothes for the cup.

Wire rope or hemp rope, tassels or other favorite decorations, solid glue. In the production process, I found a piece of discarded paper. I used the packaging of Xinjing, which is offset paper, and there happened to be printed brush words on it. It would be very ancient to make a lantern.

You can use woolen thread to make simple hairball flowers, woolen baby chicken, woolen resurrection eggs and other handicrafts. Steps for hairball flowers: The materials and tools that need to be prepared are: scissors, wool (your favorite color).Wrap the woollen thread around the fingers, about 100 times (the number of fingers depends on the size of the desired hairball).

What should I do? Just make a hanger with a buckle. Bend a small circle on the hook of the hanger, a rubber band at the bottom of the hook, and tie a small iron ring at the end of the rubber band. After hanging the hanger on the rope, put the two small circles together, and the hanger will not fall off.

Making cardboard animals: Using cardboard, colored paper, glue and other materials, you can make all kinds of cute animal models. Making handprints: You only need some watercolor pigments and white paper to let children leave their handprints on the paper, and then draw on them with their fingers to create unique paintings.

How to make small scientific and technological inventions Small electrical appliances Materials: small light bulbs, fine lacquer bagsLine We know that we usually find some old batteries in our drawers, but we don't know whether there is any electricity left. It is very troublesome to put them in an electrical appliance to check and we can't know the remaining amount of electricity. Therefore, you can make a small electrical tester.

Self-made Schauberger engineAircraft, what is the material

1. Explosive Schauberger engine: Naqi's secret weapon - the propulsion device of the flying saucer of the "Baro Goddess of War". Invented by Austrian engineer F. Schauberger, water and air are used as fuel.

2. The most magical thing is its flameless and smokeless engine, which uses water and air as the main power. To study the principle of this engine, we must first analyze it from the flight principle of the flying saucer, because the Nazi logo of the flying saucer in flight seen in some videos is facing one side when flying, saying The shell is not rotated, but fixed.

3. Stainless steel cylinder * 1 piezoelectric ceramic buzzer sheet with a diameter of 1 to 8CM smaller than a stainless steel cylinder. If you like to pack a few pieces.

The engine needs external force to start

When the engine is not started, the piston is in a stationary state. When starting, it needs to use external forces to compress the air mixed with oil to ignite. After ignition, the compressed air mixed with oil will provide energy to the piston, so that it work It is stuffed in the cylinder and moves by itself.

The role of the starting system The starting system The engine must rely on external force to drive the crankshaft to rotate before it can enter the normal working state. Usually, the whole process of starting to rotate the car engine to idle under the action of external forces is called the start-up of the engine.

Cars need external forces to start. Generally, engines have a starting motor. Rely on this starting motor to drive the engine. So that the engine can operate normally. I hope my answer can help you.If you don't understand, please continue to ask. I wish you a happy use of the car! [ If there is a problem with the car, ask the car master. 4S store professional technician, 10 minutes to solve.

Yes, all car engines are equipped with starting motors and storage batteries. When gasoline engines are running, each cylinder needs spark plugs to ignite. High-pressure discharge can ensure the operation of the engine according to the working order of the engine and the continuous working speed of the engine.
