Some toilets flush mechanisms require a long hold, some only need a light press. Others, a jab to compensate for a bad lever.
Others need some fiddling for it to go. Some you use your hand, others, you use a square of toilet paper before touching it. And a few you definitely use your foot even though you know it’s wrong, because… ew.
This is the correct answer, this also incidentally solves the debate about keeping the seat up or down.
The new toilet i just installed has a whirlpool like flush, theres not even a splash or anything it just whirls into oblivion
