Electrostatic flocking is a way to make grass in a diorama so that it realistically stands up and looks real.

You use a small hand held device that applies electro static energy to your diorama. Picture it kind of like how your hair stands up on end when you rub a balloon on your head!!

This is what the machine does. It makes the grass strands stand up straight on the diorama.

I have a video showing you what it is and how to do it right here.
