Many people enjoy making their own amateur films. While the production values are usually less advanced than those of a studio, it is possible for independent filmmakers to create some of the props or special effects they see in Hollywood films. One of the props they might want to use is safe fake glass. This is usually formed into bottles that are broken over a character's head, often in a bar fight. Creating breakable bottles is actually fairly simple.

  1. 1

    Gather your materials and choose a spot to work where the things you put together will not be disturbed before they are finished, such as a garage you can lock.

  2. 2

    Remove the labels from a beer bottle and a 2-liter soda bottle and clean them. Then use the knife to cut the top off the empty 2-liter bottle.

  3. 3

    Use a glue gun to hot glue the piece you cut off (it should be inverted) onto the top of the beer bottle. Then glue the soda bottle cap on top of this.

  4. 4

    Drill a hole in the cap and through the middle of the wooden ruler. Screw the ruler to the cap. This will act as a support when you hang the bottle. Spray the bottle with cooking spray.

  5. 5

    Place this assembly inside the 2-liter bottle, with the weight of the ruler resting on the edges of the soda bottle. Mix the liquid rubber compound according to the instructions and pour it around the beer bottle. Place a weight on top to hold the bottle down.

  6. 6

    Let the compound cure for as long as the instructions of the package suggest. Then cut away the 2-liter bottle. Cut from the top about halfway down and all the way to the inner bottle. Pry open the mould and remove the bottle.

  7. 7

    Mix 3 1/2 cups of sugar, 1/4 tsp of cream of tartar, 1 cup of light corn syrup and 2 cups of water in a pot and slowly bring them to a boil, stirring often. When the mixture reaches a temperature of 300F, remove the pot from the heat.

  8. 8

    Spray cooking spray inside the mould and tape the cuts you made in the side closed. Pour some of the mixture into the mould. Immediately tilt the mould and begin turning it as you slowly pour the excess back into the pot. The goal is to produce a hardened coating on the inside of the mould.

  9. 9

    Place the mould in the refrigerator for about an hour. Then remove the mould from the refrigerator and open the mould. You now have your breakable sugar bottle.

Tips and warnings

  • Adjust the amount of ingredients to the amount of glass you need.
  • In its molten state, you can receive severe burns from the mixture. This means that only adults should do this, and they should be careful.
