Science and technology small production of 100 kinds of practices are as follows:

One, homemade badminton

Preparation of materials: an empty beverage bottle, foam fruit net set of two, a rubber band, a glass bullet.

Making process: 1, take an empty 250 ml beverage bottle, cut off the top half of the bottle.

2, will be cut into 8 parts, cut with scissors to the neck of the bottle, and then, each part of the cut into a consistent size of the petal shape.

3. Put the foam fruit netting over the outside of the bottle, and secure it to the mouth of the bottle with a rubber band.

4. Wrap another foam fruit netting sleeve around a glass bullet and stuff it into the mouth of the bottle, tucking it in tightly and exposing it for about 1 centimeter.

5, cut off half a ping pong ball, the bottom of the hemisphere over the mouth of the bottle, four sides cut into whiskers, cover the mouth of the bottle and then fixed with a rubber band.

6, landscaping modification, a homemade badminton completed.

Two, homemade soap paper

Materials and tools: good moisture-absorbent white paper, a small piece of soap, a pen and a disposable beverage cans. Production methods: the first soap chopped up in the can, the amount of water on the cup on the stove heating, and so the soap melted, the white paper cut into matchbox size, a sheet coated with soap, and then removed from the drying of the soap paper.

Three, homemade hot air balloons

1, first we cut out 6 to 8 leaf-shaped pieces of soft paper.

2, fold them in half and glue their edges together to make a balloon.

3. Tape four strings to the bottom of the balloon. Use playdough to attach the other end of the strings to the table.

4. Set your hairdryer as slow as possible. Point the mouth of the hairdryer upwards at the opening at the bottom and turn on the switch. The balloon will slowly grow in size and pull the cord tight and off the table.
