How do you make a pop-up pyramid? like in a pop -up book when you open it something pops up in your face.?

You have to cut two slits in the back of a folded piece of paper, then glue the pyramid on cut piece, which should be fould outward from the paper. That's the easiest way, stick with it. The other way is not worth it.











The slit paper should be in two straight lines down the middle of the page and stick out like a chair when foulded outward correctly
