Final answer:
Yes, touching a conductive object before unwrapping a film helps to dissipate static electricity, thus avoiding static buildup and potential shocks.
Step-by-step explanation:
To avoid static electricity, it is true that you should touch a conductive object before unwrapping a film. This is because touching a conductive object allows the static charge to dissipate, preventing the buildup of static electricity. When materials like plastic wrap are involved, they can easily become charged through separation of charges, and this can cause them to cling to surfaces or cause unwanted shocks. In various situations, from pulling clothes out of a dryer to handling electronics or fueling a car, it is recommended to discharge oneself to avoid static shocks and potentially hazardous sparks.
