I guess this a fancy dress outing somewhere, maybe the Disney theme park that had Star Wars week. What a great mum dressing as Princess Leia and her son or daughter looking just fine as a miniature sized Stormtrooper.
Star Wars Fact - Many Dark Jedi use Force Lightning, which is a corrupted version of The Force and materialises itself as blue lightning. The Dark Jedi then directs it at their opponent. Note that the Light Side Jedi do not use Force Lightening.
