Small production for middle school students, small handmade for junior high school students

It is simple, and the use depends on the situation.

Very interesting little production is very simple, you try it, and when it is done, you can peek at what you are doing at night upstairs?

Make a periscope.

To make a periscope, you only need two small square mirrors of the same size and a piece of cardboard. If your small mirror is ten centimeters long and seven centimeters wide, then you should prepare a piece of cardboard with a width of 4 7 = 28 centimeters. The length of the cardboard can be decided for yourself according to the conditions.

The cardboard is longer, and the periscope can be made taller.

Three parallel lines were drawn on the cardboard, each with a distance of seven centimeters, as shown in the diagram. Cut off the blacked-out parts. Use a knife to make a mark along the dotted line (be careful not to cut through).

Then, fold it around the table to make a rectangular box and glue it with kraft paper.

Glue the small mirror with white tape as shown in the picture below (so that the angle between the small mirror and the long carton is equal to 45°). Two small mirrors are aligned in parallel. In this way, a periscope was made.

If the small mirror in your hand is less than 10 centimeters long, you can calculate the size of the carton according to the Pythagorean theorem, provided that the angle between the mirror and the carton is 45°. It's fun to use a periscope to ** the scenery outside the window, and you can also use it to hide and seek. Of course, periscopes were made primarily for scientific research and national defense.

Scientists use periscopes to observe the launch of rockets in the basement; When conducting atomic physics experiments, researchers use periscopes to observe dangerous experiments that are radioactive through a thick protective wall. When the submarine is underwater, it must also use a periscope to observe the situation on the sea surface.

Who invented the periscope is now impossible to find. The earliest ancient book in the world to record the principle of periscope is the Huainan Wanbi Technique in China in the second century BC. The book records such a passage: "Take a large mirror and hang it high, and put the water tray under it, and you will see the neighbors." ”

In ancient times, under the eaves of some ancient temples in the deep mountains of our country, a large bronze mirror is often hung obliquely, if a basin of water is placed on the ground within the temple gate, the mirror is aligned, this is made into a simplest periscope, and the sheep intestine path and passing pedestrians outside the temple gate will be reflected in the water.

When washing clothes, some remaining soap bars and crumbs, continue to use both fragile and difficult to use. In order to make the most of these leftover soap heads, the ordinary laundry brush was modified and the desired effect was achieved.

Modified materials: a washing brush, a thin iron sheet (preferably aluminum or copper), and a few small nails.

Method: Cut the thin iron sheet into 3 cm wide strips, then use small nails to nail around the washing brush to form a small container (soap dish) on the top of the washing brush, and then use an awl or hand drill to drill some holes between the brown hair tufts of the washing brush. Then make a lid slightly larger than the top container out of a thin sheet of iron to cover the soap dish.
