Pictures and production methods of scientific and technological small production (to be done well)

1. First, we cut 6-8 leaflike pieces of paper from soft paper.

2. Fold them in half and stick the edges together to make a balloon.

3. Stick the four connecting wires to the bottom of the balloon with adhesive tape. Fix the other end of the line on the table with plasticine.

Try to set the speed of the hair dryer very slowly. Aim the air outlet upward at the opening at the bottom, and then turn on the switch. The balloon will gradually get bigger, tighten the line and leave the table.

2. Self-made wall-mounted flower basket

Materials and tools: two sprite bottles, glue, meat cleaver, scissors.

Production method:

1. Remove the green bottom cover of Sprite bottle, cut it into lotus shape, turn it over and stick it on the bottle body to form the base.

2. Cut a 2 cm wide green ring from the green bottom sleeve and put it on the bottle.

3. Remove the bottleneck, and cut a 13cm long, 8cm wide wideband and several 3cm wide narrowband on the bottle.

4. Carve a pattern on a 3 cm narrow strip with a meat cleaver? As shown in figure 3, then fold these narrow strips outward and insert the green ring from bottom to top.

5. Take another beverage bottle, use the bottle body and cut out 6 leaves with scissors, the length is 17 cm.

6. Nail the flower basket on the wall, insert leaves and flowers, and the wall-hung flower basket will be ready.

3, homemade soap paper

Production materials and tools:

White paper with good water absorption, small pieces of soap, writing brush and disposable beverage cans.

Production method:

Chop up the soap first, put it in a jar, put a proper amount of water in it, heat the cup on the stove, and when the soap melts, cut the white paper into the size of a matchbox, coat it with soap one by one, then take it out and dry it in the shade, and you can make soap paper.

4, homemade flashlight

The specific manufacturing method is: lift one end of an abandoned can (such as Lulu beverage can) and beat the other end with a round hammer. Roll up two 1 batteries with thick corrugated cardboard and put them in a can, with the positive pole facing up and the negative pole facing down. Find a suitable plastic cover (for example, the magic big roll cover can just be buckled on Lulu's beverage can), and dig a round hole in the center of the cover, the size of which is suitable for the light bulb to be inserted tightly. Insert the bulb base into the small hole. Take a section of tracing wire, peel off the wire skin at both ends, wrap one end around the lamp cap, and tie a small hole at the other end from the side of the plastic cover. Put the plastic cover on the jar. Check whether the bulb and battery are in close contact. Disposable flashlights will be ready here. When in use, press the wire on the side wall with your thumb on the unpainted weld away from the can, and the flashlight will glow. When your thumb jumps off the wire, the flashlight will go out, which is very convenient to use.

Step 5 clean the eraser with a brush

If you make a mistake, use an eraser. After wiping, there will always be a lot of debris left on the paper. It is unsanitary and troublesome to pat by hand or blow by mouth. It won't be so troublesome to make a clean eraser.

Material: large rubber, waste brush.

Tools: scissors, glue.

Production method:

1. Dig a small and shallow round hole at one end of the rubber.

2. Remove the tip of the waste brush, clean and dry it.

3. Cut off the tip of the brush head to make it a small brush.

6. Make a pen container!

Do you have any unused glass cups at home? Or a broken teacup, try it, as long as it is heavy enough to hold a pen. Find a beautiful cloth, or colored paper, and make a dress for the cup. Kraft paper is also good. Wrap it in a cup, measure it well, cut a suitable piece, and leave a margin of about one centimeter at the joint. Find some glue, paste, all-purpose glue and stick the coat on the cup. Chewed gum will do. Chewed gum should be pulled down a little. It is important to stick the edges and seams tightly. That's about it. Trim the untidy place, stick an ornament casually, and write a few words with colored pens, and it's done.

No decorations? Find a pictorial, cut some beautiful ribbons that fall off your clothes, or draw them directly.

Well, your work is over.

4. Insert the brush head into the small round hole of rubber and stick it firmly with glue.

Ok, the clean eraser is ready. Whenever you finish wiping the eraser, you can gently "sweep" the crumbs off the paper with a brush and then pour them into the wastebasket.

Step 6 make a flat glass

Method one

"Materials": table tennis, rubber balls, white latex, rags or scraps of paper, plasticine.

(1) Open a hole with a diameter of 3 cm at the top of the rubber ball, and fill the bottom of the ball with plasticine equivalent to about one third of the ball to make the body of the tumbler.

(2) Glue the ping-pong ball to the small round hole of the rubber ball with white latex to make the head of the tumbler.

(3) Cut out the five senses and limbs of the tumbler with cloth horns or colored paper and stick them on the head and body respectively.

Method 2

【 Materials 】 Rice, bowls, chopsticks, toilet paper and eggs.

[production process]

(1) Poke a hole in the top of the egg with chopsticks, stir the egg white and egg yolk with chopsticks, let the egg yolk and egg white flow into the bowl, rinse with water and dry with toilet paper.

(5) Draw a face, eyes, nose and mouth for the tumbler.

Method 3

[Materials] Cardboard, table tennis, steel balls or glass balls, crayons, art knives and latex.

(4) Draw your favorite animal head on the outside of the cylinder.

A little animal that can somersault has been made. Put it upright on a page, push it gently, and it will somersault forward.
