In the quantum world actually nothing ever make contact with each other, meaning there are no 2 atoms making any physical contact but it's the gravity of each atom pulling other atoms near each other.

Every thing kind of works like magnets constantly electrons moving very fast and the negative and positive(polar affects) is shifting in nano seconds so before moving apart they pull back near each other and before colliding they move apart, now imagine infinite numbers of atoms in the universe are doing this non stop, just like when you play with 2 magnets when they pull and turning one magnet makes them to push outward.

Now with all that said yet I dropped my wafer with honey on it on a sheet in my bed and picked it up almost after 1 second, though I knew it is already contaminated but as nothing big was visible I ate it anyways. :)
