Bending plastic with a hair dryer is a common technique used to create curved or shaped plastic items. Here are the steps to follow:

  1. Choose the right type of plastic: Not all plastics can be bent using a hair dryer. Plastics that are thin and flexible, such as polycarbonate, ABS, and PVC, are ideal for this technique.

  2. Clean the plastic: Make sure the plastic is clean and free from any dirt or debris before heating.

  3. Heat the plastic: Hold the hair dryer 2-3 inches away from the plastic and start heating it in a back-and-forth motion. Make sure to keep the hair dryer moving to avoid overheating any one area.

  4. Bend the plastic: Once the plastic has been heated enough to be pliable, carefully bend it to the desired shape. Use gloves to avoid burns or cuts from sharp edges.

  5. Hold the shape: While the plastic is still warm, hold it in place until it cools and hardens. This can take several minutes.

  6. Repeat if necessary: If the plastic does not bend to the desired shape or hardens before you can shape it, you can reheat it and try again.

Remember to always use caution when handling hot plastic and to work in a well-ventilated area to avoid inhaling any fumes.
