A hologram chamber resembles an alien flying saucer. The disc-shaped chamber has a round opening in the top disc that allows viewing of an object placed in the chamber. A small item placed in a hologram chamber will look as if it is floating when you look into the round opening. Hologram chambers are normally metal or hard plastic. The entire inside of the chamber is coated with a reflective mirror. The two parts of the chamber look like soup bowls with a hole cut in the bottom of one.

Purchase or find two identical-sized metal or plastic soup bowls. Turn one of the bowls upside down so the bottom is facing up. Mark the centre of the bowl with a pencil.
Drill a hole through the bottom centre of one bowl, using a 1 1/2- to 2-inch carbide-tip hole saw bit. Drill slowly so the bowl does not shatter or bend.
Sand the cut edge lightly until it is smooth.
Turn one bowl upside down and place it on the centre of a piece of paper. Trace around the outside of the bowl top. Remove the bowl. Draw a second circle 1 inch away from the traced line. Cut out the shape along the second circle.
Lay the reflective window film on a flat surface. Place the paper circle on the edge of the reflective film. Draw around the circle. Repeat the process to make a second circle. Cut out the two circles.
Place both soup bowls on a flat surface with the inside of the bowls facing up. Carefully remove the backing from one circle of reflective film, pulling it from the edge of the film to the centre. Stop at the centre.
Lay the film in one soup bowl, carefully centring it. Gently smooth the reflective film into place, making sure to avoid any wrinkles. Begin at the centre and work toward the outside edge.
Remove the remaining film backing as you attach the film to the opposite side of the bowl, carefully smoothing it into place. Repeat the process with the second soup bowl.
Push the tip of a craft knife carefully through the reflective film that is covering the hole in one soup bowl. Cut around the edge of the hole to remove the film.
Place a small object in the bottom of the soup bowl without the hole. Flip over the soup bowl with the hole so the hole is on top. Line up the edges of the two soup bowls. Place the soup bowl with the hole onto the bottom soup bowl to create the hologram chamber.
