How to Make an Inflatable Cube Out of Paper

First, fold one sheet of square paper in half horizontally to create a crease guide and then unfold the sheet of paper.

Next, fold the sheet in half vertically to create a crease guide and then unfold the sheet of paper.

Now, fold the sheet in half diagonally (top right corner to lower left corner) to create another crease guide and unfold the sheet of paper.

Once again, fold the sheet in half diagonally (top left corner to lower right corner) to create a crease guide then unfold the sheet of paper.

Next, fold in the two side creases on the sheet until they form into a pyramid shape.

Fold the triangle corners up in half so they meet at the top point. Repeat on the other side of the triangle shape.

Next, fold the right and left corners to the center of the diamond shape. Repeat on the other side of the diamond shape.

Now fold down the small left and right side triangles in half so they meet in the center. Repeat this step on the other side.

Unfold the larger left and right side and fold down in the small triangles (same triangles folded a couple steps earlier). Repeat this step on the other side.

Tuck in the small triangles gently ,as you do not want to break the corners (Repeat this step on the other side).

Finally, blow into the hole at the bottom until the cube is inflated.
