This is the math section but ok
if yo mean the pyramid shaped thingie then
get a square piece of paper (4 right angles, equal length sides)
fold the paper in half so one corner touches the opposite corner
unfold
repeat but with the other corner that doesn't ahve a crease
unfold
you should have an x in the middle of the paper with 2 valleys facing up
now fold the 4 corners to the middle of the x so you have a smaller square now
flip it over so the flat side is facing you
fold the 4 corners in to the center
fold the square into a valley horizontally
unfold
fold the square into a valley vertically
unfold
flip it over and pry out the 4 corners and manipulate it like in the illustration
