MacGyver is in another tight spot.
He has been locked in the kitchen supply area of a military camp.
Unbeknownst to his captors he has concealed an electronic homing beacon in his shoe --
he will simply wait for Pete to arrive!
Unfortunately his foot was run over by a humvee in the excitement of the chase and
he suspects that the capacitance unit of the tuning circuit is now malfunctioning.
What to do?
Mac recalls that the circuit specs called for a 0.02 microfarad capacitor. Looking through the supply cabinets he finds a roll of wax paper and a roll of aluminum foil. He will make a new capacitor!
Recalling a formula from the most useful and interesting class from his college days, he begins some quick calculations:

|Finally Mac places the two sections of foil between alternating layers of wax paper. Rolling the sandwiched layers up tightly with a rolling pin, to get a uniform separation of the two conductors by the amount of one layer of wax paper, the capacitor is formed! Pulling out a few paper clips, appropriate connections to the homing beacon are made. Mac is rescued soon thereafter!|
