I went to a puzzle exibit, and there was a guy assembling a V7. I was cool.
There were some puzzles put out for people to play with, and one was a magic. (I think that wasn't very smart for whoever put it there. It was broken apart.)
my way to break in:
choose any edge and pull it apart so that there are 3 pieces on the right and 4 on the left. then put your thumb in between. and push to the right until those two wings come out. then you can simply go on taking out some center pieces and then fully disassemble the cube.
