The Human Crane

Have you ever noticed that giant cranes just appear? Who puts them up, or more importantly, how are they put up? In this team game, the challenge is to impersonate a crane engineer as the little animals need rescuing!
  • In this competitive game, participants have to build a contraption to collect balls and little animals from a ball pit for their team. Knowledge of engineering and well-oiled teamwork will help. Don't worry if either of these is missing, because it's in the competitive moment that the best ideas are born.
  • Number of participants: up to 25 people
    For larger groups, games can be run in parallel.
  • Set-up and clean-up: 15 min + 15 min
  • Game length: 1 hour
  • Required outside of AHHAA: a room with tables for 5 teams and a competition area; electricity available if possible.
  • Price: €240+tax
