Cube Libra: very nice version

If you do not do this effect you should. It is literally amazing to watch.  OK you have to practice until the moves become second nature but doesn’t everything that is really good require practice?  I wont insult you by going through the effect but i will see this is the cleanest method for pickup of the stack that I have ever seen.   It is a pressure plate.  It requires no unusual moves, no flipping of contraptions.  He act of picking it up either releases or locks the stack, whichever you prefer.  . This is nice prop!  I unwrapped it to photograph it.  The other stack of numbers is in the tube still in tissue paper.or
