Lego: Back in the days of the crazy cults movement this might have been a useful part of an initiation ceremony. You could tackle it dry as suggested above or of course add petrol and a lit match for the full early disciple, hot, sticky and life changing experience. Those who fail or refuse can't ever join but might be able to walk home from the meeting physically unscathed though some kind of mental health damage is likely. Anyway the abstract plastic hail storm that is deconstructed Lego remains both a marvel and a baffling enigma for most adults.
Many modern homes will have a bin full of it somewhere, all the stray pieces that are never likely to be reconstructed into anything remotely recognizable making this also a study of pain, frustration and considerable expense. It could fit nicely into your team building sessions as an extra task if such things are still common in the workplace. Otherwise very useful as a prank when carefully set up on the parent's bedroom floor for late night high jinks and swear fests. All of this is very good for the Danish economy and certain aspects of Viking mythology.
