Level of difficulty I would say is 1
BEST PART
Its VERY VISUAL - you could show this effect 1 inch away or 10 feet away
It packs small its easy to make and its fun to perform - what more can or need be said... only gimmick I carry regularly, bar a DB and a star shaped band...
did I mention.... ITS VERY VISUAL
As for handing it out - why would you need to - use it as a simple/quick opener or filler - or when out and about and you want to gain someones attention
