Well, we all know the old classic jumping coins,when the performer shows one coin in each hand,and throws one to the other hand when they close it,and then open to show one has jumped. Here is a great  improved  version which  uses four  coins .
Take four quarters(I am british so I use 10p coins)and place one coin in each hand,close it into a fist and place the other two on top of the closed fist.Then it looks like you do it wrong,and dump them onto the table,but your really doing a secret move.You are really just letting both of the left hand's coins and letting the right coin on top fall in to the hand.Then say that you get a little excited when you do it first. Then try again and place the two coins  from the table  onto your  hands and let them fall into each hand. Then the magic has happened!!!
