Three wooden blocks labeled "A,B, & C" and a square tube are displayed. Block "A" is removed and placed in a hat. The remaining two blocks are covered with the tube. The audience is askedthe location of block "A". Naturally they say "in the hat" and you remove the block to show that they are correct. The tube is also lifted to show the position of the remaining two blocks. Now for the magic. Block "A" is placed on top of the other two blocks and the entire stack is covered with the tube. The audience is now asked the position of Block "B". No matter their response they will be wrong. The tube is lifted and block "B" is gone even though it was between two other blocks. You then reach into the hat and remove block "B". This is a true mystery that will have their heads spinning. Nicely crafted from wood.
