As i said in the title.You need to have the perfect setting in order to pull this off.
First of
all,it requires a little setup.So,forget the idea of just cutting a leaf from a tree in front of
them and start performing.Also you need your leafs to be specific.The tearing of the leaf(1 of the
leafs that you are holding has a tear),which is already done as you approach your spectator. No
tearing happens in front of them.You make a buritto shape of the leafs (1 with a tear one with no
tear) and you give them to the spectator in order to hold them behind their back and grab the 2
stems of the leafs,so they end up with one leaf in each hand.At that moment technically ,they do the
clean up for you but if the ground is not what you want it to be (if you buy the trick you will
understand what i am talking about) they might find out something on the ground some seconds after
the trick.
Αll in all,in order for this trick to work you need a lot of parametrs to be 100%
correct.
