It's always fun to hand them out and watch people sit and try to solve them, often for hours at a time. You can watch them pass out, their faces vacillating between strained concentration and frustration as they try again and again. They can also observe the people around them. You could hold something for a minute. Do not forget that you can get different difficulties. In our family we are at about the fourth level. Someone is bound to solve it, but it can take hours. The solution requires not only understanding the problem, but also finding the right way to keep all the pieces in the right configuration, and then making the right moves in the right order. They usually sit on the table in my mother-in-law's living room for a while. once they are resolved. For example a phone call for the next visitor. Or something to try again in a few weeks if you've lost the muscle memory you've developed to solve them the first time.
