MacGyver builds a telescope using a newspaper, a magnifying lens, and a watch crystal (the crystal covering). He rolls the magnifying lens and the crystal into the newspaper, making a telescope. In order to fake a hand print for electronic scanning, MacGyver spreads a thin layer of plaster dust over the scanner. Some of the dust sticks to the sweat left on the scanner by the previous user. He blows away the excess, covers the sensor plate with his jacket, and presses down lightly with his fingers. Macgyver uses a ladies room mirror shard, and janitor's mop and bucket to redirect a laser defense grid's lasers back into itself and destroy it.
As laser-wielding robots home in on his body heat, MacGyver creates a fake heat signature by using magnets wrapped in burning paper. He throws one piece of burning paper and magnet at each robot. The magnets stick to the metal of the robots. With each robot "tagged," they home in on each other and destroy one another.
