Video of folding method of tin foil ingot

Folding tin foil ingots is very simple, and the steps are as follows (better understood with pictures):

Take a piece of tin foil to about one-third of the position, and then fold it in half.

Then fold along the other side produced by folding in half, that is, fold the shorter part along the line.

Take out more than one third of the shorter part of the folded upper part, and then fold it in half along more than one third of the line.

Cover the part just turned over by more than one third with the longer part below (that is, the part turned over for the first time).

Refer to the above picture.

Fold more than one third of the first folded part obliquely (it must be folded together with more than one third of the second folded part), that is, fold along the position marked by the "yellow line" in the above picture.

Fold the excess top half along the edge and press the two isosceles right triangles that open below.

Hold the two corners of the ingot with both hands and shake it gently, not too hard, or the ingot will not shake.

Fold it several times to find the feeling and find the right position to fold it.
