The manufacture and processing of simple and scientific gadgets

Small scientific products are relatively simple, and the production process is as follows:

Aluminum foil rocket, preparation materials: black cardboard, aluminum foil paper, red paper towel, handmade white glue or tape, pencil, scissors.

The specific steps are as follows:

1. Draw a rocket shape on the aluminum foil and cut it out. Tear a piece of red paper towel in half and stick it on a black cardboard to make a fire-breathing shape. Then stick the aluminum foil rocket on the black cardboard to cover some "flames" slightly, and stick some shining stars around the rocket.

2. Paper tube rocket:

Preparation materials: scissors, glue or tape, pencil, toilet paper roll.

Wrap the paper tube with colored paper, and cut the paper with the length of toilet paper roll and wrap it. Cut the colored paper into a fan shape, roll it into a cone shape, and stick it on one end of the paper tube. Cut three small discs and stick them in front of the paper tube; Cut two small triangles and insert them on both sides of the paper tube. Finally, cut some paper and stick it on the inside of the bottom of the paper tube. The rocket to space is ready!

3. Hubble Space Telescope:

Preparation materials: toilet paper roll, aluminum foil paper, bamboo stick, cardboard, handmade white glue.

Punch holes on both sides of the toilet paper roll, pass them through with bamboo sticks, wrap the paper tube with aluminum foil paper and fix it with white glue. Cut two square pieces of cardboard, fold them in half and stick them on both sides of the bamboo stick. Our Hubble telescope is finished.

4. The Big Dipper:

Preparation materials: blue or black cardboard, cotton candy, toothpicks.

The Big Dipper in the sky is spoon-shaped, which is the easiest to identify. It is also an important group of stars that indicate the direction and know the constellation. We string toothpicks and marshmallows into the shape of the Big Dipper, stick them on cardboard, and sprinkle some stars around them as decoration.
