This effect really works. But I am a little disappointed that so much has been said in the reviews
of the need to use a jacket. What could be more natural than taking off your jacket because you
explain that the effect requires a lot of effort. Next, you provide a reason for holding the jacket
in front. Simple, you explain that as hot air rises so you must keep your legs warm. simple isnt it
when you think about it. Remember even the best trick is bad unless it has misdirection and
presentation.
