New Melting Block by John Rausch is an improved version of Tom Obeirne's original Melting Block puzzle. This paradoxical 3-D packing puzzle has two unique assemblies, one using seven pieces and the other using all eight. There are two possible solutions for each assembly.

The seven-piece solution seems to fill the box entirely, with little room to spare. The leftover block seems far too large to fit in the box...yet somehow, impossibly, the eighth piece does fit when the second solution is discovered.

NMB is the result of an exhaustive mathematical analysis. Of all possible piece subsets and assemblies, over 33 million solutions were reduced to two possibilities. New Melting Block is far more difficult than the original Melting Block and a wonderful addition to any collection.
