How to make a tech craft

Make a tech craft as follows:

1. Make the base of the pitcher. Bundle 3 pencils together, the rubber bands should be located one inch below the ferrule (metal part) on each pencil. Tie two pencils together with gray rubber bands and push the other pencil on top of the tops of the first two pencils.

3. Start making the launch arm. Place two pencils side by side, then a third pencil, which should overlap the other two pencils by about 2 inches. Use two rubber bands to ensure a strong connection. Cut off the bottom of the mineral water bottle, about 2 inches deep, to create a basket for the pitcher.

5. Cut two holes on either side of the basket near the base for the pencils on the launch arm to pass through. Slide the basket into the extended pencil on the firing arm, then tighten a thick rubber band around the top of the pencil. This will serve to stop the basket from slipping off during firing.

7. Rubbermaid can be glued to the basket in contact with the pencil and this will help to reinforce the basket. This is not a mandatory step. Glue a thick rubber band about 2 inches from the bottom of the pencil in the middle of the base, and tie the bottom of the launch arm under the thick rubber band we just made so that the launch arm is pointing straight up.

9. To launch, start by unfolding the legs of the pitcher by pushing the center pencil of the base between the other two legs of the base. Place one hand around the base so that your palm is in contact with the center leg, your thumb is in contact with one leg, and your fingers are in contact with the other leg. Use your free hand to pull back on the launch arm and release it, remembering to place the projectile in the basket.

Making science and technology crafts requires choosing the right materials, using the right tools and methods to do it, and gaining experience.

I. Choosing the right materials

1. According to the specific purpose and requirements of the crafts, choose the suitable materials;

2. You can use spare parts from used electronics, discarded circuit boards and so on;

3. You can also use some common materials, such as glue, wires, cardboards and boards.

Two, the use of appropriate tools and methods

1. To master the production steps and basic common sense, such as welding, cutting, sanding and other operations;

2. It is recommended that the use of efficient and safe power tools, pay attention to the safety of the use of;

3. Acquire a certain degree of numerical ability and experimental ability for the technical support for handicrafts.

Three, keep accumulating experience

1. Accumulate experience in creative exploration, keep trial and error and summarize;

2. Seek help from official websites, forums and social networks, ask for advice from others more often and absorb the skills;

3. Continuously learn and study the knowledge related to science and technology handcrafting in order to improve their skill level.

Four, expanding knowledge

1. Science and technology handicrafts encompass many fields, such as robotics, electronic music, smart home and so on;

2. Beginners can participate in the DIY community and workshops to learn more;

3. Making science and technology handicrafts need to pay attention to the safety of, such as the circuit board in the Toxic substances, electromagnetic radiation of electrical equipment, etc.;

4. Should develop good civilized habits, to do garbage classification and disposal, to protect the environment.
