Sorry it took so long to get this up.
Basic Multiplying SpngeBall thing
First, you choose a spectator to come up. And, before the performance, conceal a sponge ball in your hand, now, have the three sponge balls on the table, ask the spectator to pick one of the sponges, pick up the sponge that he picked with the hand that has the concealed sponge in it, and then press them together, the spectator thinks you have one, but you really have 2. Place them into the spectators hand. tell him to squezz on to it tightly.
then, pick on of the remaining 2 sponges that is on the table.
But pick it up w/ your right hand, and pretend to put it in your left, the spectator will think you have one in your left hand, butit is still in your right, this requires practise, now open your left hand and show that there is nothing in it, then tell the spectator to open his hand, and find 2, now you still have a concealed sponge in your right hand, so do the same thing to make three in the spectators hand.
One and One makes Three
You only need 3 sponges in this trick. have one concealed in your hand, and the other two on the table. Tell the spectator that he cannot add. While you are saying this, pick up the two on the table, and place them in his hand, ask him how many balls are in his hand, he will say two, he open it and there are three.
Takes practise.
Strange Subtraction
Have 3 sponges on the table and one in your pocket, as you talk steal the 4th from your pocket. and keep it concealed in your right hand which should hang at your side. Hold open your left palm, with the right hand pick up one of the sponges on the table adding it to the concealed one; place both together in your left palm and close your left hand. As you do this say: "If I take one sponge and put it in my left hand, stop talking, pick up one sponge fromthe table with right hand and put it in left hand. And continue........"and then another in my left hand"... Now, pick up the last sponge with right hand and place hand and spnge in right pocket. "And I put one inmy pocket, how many are left in my hand" The spectator will say two, then open your hand and ther eare three.
The Climax
Have three sponges on the table and one concealed in your right hand. you pick up the three sponges with your hand that has the concealed sponge in it and place it in spectators hand, now tell him to close tightly and then openit, there are now 4!
