CUBE, PYRAMID, HEART AND FACE SHAPES

First the world was introduced to the cube shaped watermelons, next came the pyramid shaped ones, then the heart shaped followed and now there are some faced shaped ones as well. Wow! I wonder what shape they will come up with next?

Here is how they make them:

All they do is put a glass / plastic container around the small, baby watermelon, and it grows into the shape it’s put into. Cube shaped is put into a cube container, triangle into a triangle container, etc. They do something extra fancy with the Hitler face though, but the method is kept a secret by the inventors.
