hes holding a pen
in the last two pictures the people were split into teams and given certain equipment. cant remember exactly what it was. they had to create the tallest tower, using only what they were given without talking to each other. it was something like 6 sheets of paper, some paperclips, blu tac, a couple of pens and some carrier bags. (not sure though)
the game in the top picture is way too complicated, id give it a miss.
