      Use scissors to cut the plastic bottles into small pieces. Make the pieces small enough to fit inside the metal container.
    • 2
      Place the pieces of plastic into an oven-safe metal container. To prevent melted plastic from spilling inside the toaster oven, do not overfill the container.
    • 3
      Take the toaster oven outside and heat to 250 degrees Fahrenheit. Melt plastic outside in order to avoid overexposure to harmful fumes.
    • 4
      Place the metal container in the toaster oven for three to four minutes. Increase heat in 25 degree intervals until the plastic is completely melted. Different types of plastic have different melting points (see Resources section).
    • 5
      Use protective gloves or oven mitts to remove the metal container from the toaster oven once the plastic is completely melted.
    • 6
      Use a wooden stick to pour the melted plastic into a mold. Allow the plastic to completely cool before taking it out of the mold.

    Plastic bags can be melted and fused with an iron.

    You can make your own plastic figures, craft pieces or fishing lures at home. If you can find the desired mold and the plastic, you can make just about anything. When working with plastic, try using craft plastic or plastic bottles. Melting thin plastic, such as plastic bags, can be quite messy. If your project requires you to melt plastic bags, use an iron instead of the microwave. Once warm, but not melted, plastic can be manipulated by hand into interesting shapes.

    Wipe the mold clean and place on a hard surface. Liberally spray the mold with a mold release. The poured plastic may not come out of the mold if a mold release is not applied.

    Cut your plastic into small and thin pieces. You can use plastic from fishing lures (the worms), bottles and a craft plastic. Craft plastic can be purchased in a variety of hobby stores.

    Open all doors and windows. When plastic is melting, it emits a strong smell.

    Place the plastic in the glass measuring cup. Do not fill the cup more than halfway. Heat on high in a microwave for 30 seconds, then stir. Continue until the plastic has a syrup like consistency.

    Pour the melted plastic directly into the mold and air dry. If you need the molded plastic pieces soon, place them into the freezer for an hour.
