How do i properly write a plot twist in a story?

its a step by step procedure

Explanation:

first you need to find out the root of the whole story

and how the story gradually unfolded

ok so like i went to wiki and looked up the (constitution x new "hammystan")and it showed me the picture it highlights new hampshire and says first and second session and than it says that they hit up the u.s and was like "ey dude that paper u sent us was adopted it bro thx" xd syays it all on wiki/the pic

i dont really like reading so i guess other people might not like reading either so   imma put the answer in bold italics
