The small production and production methods of science and technology are as follows:

1. Homemade badminton

Prepare materials: 1 empty drink bottle, 2 foam fruit net covers, 1 rubber band, 1 glass marble. Production process:

Take a 250ml empty beverage bottle and cut off the top half of the bottle; Divide the cut parts into 8 equal parts, cut them to the neck of the neck with scissors, and then cut each part into the shape of petals of the same size.

Put the foam fruit net sleeve on the outside of the bottle and fix it at the mouth of the bottle with a rubber band; Wrap another foamed fruit net around a glass marble, stuff it into the mouth of the bottle, plug it tightly and expose about 1 cm; Cut off half of the ping pong ball, cover the bottom of the hemisphere on the mouth of the bottle, cut the four sides into a whisker, cover the mouth of the bottle and fix it with a rubber band. After beautification and retouching, a homemade shuttlecock was completed. Hit a dozen with a badminton racket.

2. Homemade soap paper

Materials and tools: white paper with good moisture absorption, small pieces of soap, a brush and disposable beverage cans. Directions:

First, chop the soap and put it in a jar, put the cup on the stove after filling it with an appropriate amount of water, wait for the soap to melt, cut the white paper into the size of a matchbox, apply the soap liquid one by one, and then take it out to dry it to become soap paper.

3. Homemade hot air balloons

First of all, we cut 6 to 8 leaf-shaped pieces of paper out of soft paper. Fold them in half and glue their edges together to make a balloon. Tape the four wires to the bottom of the balloon.

Attach the other end of the thread to the table with plasticine. Try to turn the speed of the hair dryer as slowly as possible. Aim the blower up at the bottom opening and turn the switch on.

The balloon will slowly grow larger, tighten the string, and leave the table.

4. Homemade flashlight

The specific method of making it is to remove one end of the lid of a waste can (such as a Lulu beverage can) and knock the other end with a round hammer. Roll up two No. 1 batteries with thick corrugated cardboard and put them into the tank with the positive electrode facing up and the negative electrode facing down.

Find a suitable plastic lid (such as the magic big roll lid that fits nicely onto the Lulu can).

Dig a small circular hole in the lid** of the box, the size of the hole is suitable for the bulb to be plugged in tightly. Insert the base of the bulb into the small hole. Take a piece of wire hunt and peel off the wire skin at both ends, wrap one end around the lamp base, and pierce a small hole through the side of the plastic cover with the other end.

Place the plastic lid over the can. Check that the bulb and battery are in close contact.

At this point, the disposable flashlight is ready. When using, Xian La uses his thumb to press the wire worn out of the sidewall on the weld seam without paint from the can, the flashlight will glow, and the thumb will leave the guide brother to jump back to the slip line, and the flashlight will be extinguished, which is very convenient to use.

The easiest way to make a tech crizy is as follows:

1.Egg picker:

Find a bamboo tube about 25 centimeters in diameter, slightly larger than the diameter of duck eggs, seal the end of the bamboo joint, and saw the other end into a bevel. Cut off diagonally along the quarter of the round end face of the bamboo tube. Then put the wooden handle on the side of the bamboo tube, and the production is finished.

When in use, the bamboo tube is laid flat on the surface, and the oblique mouth is towards the duck egg, and the egg is pinched into the tube. Pick up five eggs and put them in the basket.

2.Self-feeder:

Nail the root column on the side of the sink, and nail the column with two lead wire bent bottle clamps. Pour some water into the sink first, then fill the bottle with water, plug the mouth of the bottle with your fingers, and place the bottle upside down so that the mouth of the bottle is next to the surface of the tank. Loosen your fingers, bottle water flows in parallel, and air pressure works.

The chicken drinks water, the water surface of the tank is lowered from the mouth of the bottle, and the air enters the water bottle from the mouth of the bottle, and the water flows into the tank. The bottle mouth of the tank is flush, and the water flow can automatically add water to the water feeder.
