There are many scientific projects quickly and simply to these days. However, there is a kind of project that is actually very simple, but it is also very attractive and unusual. This particular project involves magnetism. You have to do only what is necessary for the magnets. The remaining elements are readily available. Look around the house and you will find many of them.

The ingredients are needed to achieve the following:

- A few small cars – preferably four plastic toy cars.

- Donut Magnets – get twice the number of ring magnets that the number of cars that can be used. In fact, the more you use magnets, the better the result will be.

- Case elongated cardboard, preferably of the type used to keep order Tubelights.

- Transparent duct tape and scissors.

- Thermocol.

- Colored paper and other toys for the decoration of the house.

The first step is to figure out which pole ring magnets, such as Poland each have magnets in the proximity of a magnet as standard. As soon as the same in each pole ring magnet found, add magnets, toy cars with tape so that the same poles facing outward.

Now for the tracks – as an article in the width of the cartons. Only half is used for the experiment. It should be the same width as that of toy cars, and about two feet long. Now they organize thermocol with a slight angle (approximately 3 to 5 degrees) on the horizontal plane. Set a block of thermocol in a dead end. At the top, about a foot of the trail parallel to the horizontal plane to leave. Line up the cars one by one. Thermocol place to support blocks at regular intervals along the landing path in order to provide all. Also, make sure to recognize that the sides vertical. Otherwise, the cars go.

Now driving a car, in the title and release. They reach the ground. However, the neighboring cars would never touch because of the repulsive force created by the like poles of the magnet, and you can see approaching a spring-like every time a car is to the last.

This quick and easy science fair project can be decorated with colored paper and toys. It shows that the same poles of two magnets repel each other.
