Instructions
Measure the diameter of the spotlight with the tape measure. Make a note of the measurement.
Divide the diameter of the spotlight by two to obtain the radius. Set the compass to the radius and draw the outline of a circle on the purple plastic sheet with the felt tip marker.
Set the compass to 1 inch and draw a small circle in the middle of the larger outline. Cut out the outline for the larger circle with the scissors.
Cut a piece of masking tape to the shape of the 1-inch circle. Place the masking tape over the outline on the round piece of cut plastic.
Place the round piece of cut plastic on the newspaper. Paint the surface of the plastic by using the black spray paint. Allow the paint to dry for at least 1 hour and then remove the masking tape.
Set the plastic gobo over the spotlight and secure with the gaffers tape. Turn on the spotlight to see the laser effect of the light beam.
