I cook popcorn in my 700W microwave using a hard plastic contain designed for this. After dumping out the popped popcorn there are usually tiny fragments of the popped kernels left inside the container. If I put my hand OUTSIDE the container near such a fragment, it moves away as if repelled by a static electic charge. What's truely wierd is if I put my hand INSIDE the container near a kernel (not touching anything) I see no such repulsion (nor an attraction). What's going on, why does the placement of my hand make a difference?
