I did this trick at a school assembly last week of over 400 primary school kids and the reactions
were amazing as I heard many of the kids and teachers exclaiming OHHHHHH!!People on the side didn't
really see it. I also did it at a small 8th birthday a few days after. I think the kids were a bit
close and really didn't get the full effect and some kids didn't really focus on it.The adults at
the back enjoyed it.Only con is it doesn't quite fit in my case; although I'm glad its big enough
for every one to see. I may look into the folding one but not sure about the quality.
