Magic Tricks

Let's resume the concept

You can borrow a bottle (yes you can do it with some public management
i did it)
and make their water freeze (it is possible yes ;-) with some conditions at the end but easy to conceal if you are the best magician in the world like you think, you can make the story happen

It is visual ;-) simple ;-) and you can have the gimmick ready to go

So great effect Arnel seems to think about the effect more than the method but even the method is very interesting
straight to the point and so deceptive at the end ;-)

All the best
