Oh gosh, you seem so genuinely distressed. Let me calm you with my science.

As I understand it, all substances are composed of millions of molecules, and the stickiness of the substance depends on the charge of the molecules—and therefore how much the molecules of two substances are attracted to each other. Attractions between any two molecules are electric and are based on Coulomb’s Law, which states that positively and negatively charged molecules are attracted to each other, and that the charges of the molecules are directly proportional to the strength of the bond.

There are different types of intermolecular forces, but to give a short answer, just know that stickiness is caused by the electrostatic charges of molecules attracting them to one another—so when you peel sticky tape off a present, what you’re actually doing is breaking intermolecular bonds.
