Eli5: How do iPhones fake Taptic feedback buttons feel so real?

When I first got my phone I didn’t even realise my home button didn’t have moving parts until about a year in. How in holy hell is this illusion so effective and how does it work?

Your phone vibrates a bit when you push the button. It does one oscillation (there's a very tiny motor with an unbalanced weight that spins only once around for each click). Your phone, being a computer, is exceptionally fast at reacting. Your hands, being made of meat, are not nearly as fast at detecting. To your brain (which already messes with your perception to compensate for nerve lag), it can't consciously distinguish any disparity between a mechanical click and the artificial one. Your own expectations that it will click make the illusion even harder to break.
