Ken(also a STEM Ambassador) and I have this joint presentation  which demonstrates static electricity and electrons which, although not visible, make their presence felt!  We bring along a Plasma Ball, a Wimshurst Machine and a Van de Graaff Generator.  This presentation is best in a darkened room and there is no charge, as no costs are involved.  The emphasis is on fun, with a big Wow factor.
