I was passing a security checkpoint for the library when I was randomly selected to have my bags searched. I tried to not appear nervous because my brother had previously told me to pack a car battery in my bag for him. In order to pass through the game I had to play a game where my objective was to stop a metal ball from rolling to the bottom of the wooden maze board by placing rooks and green Mentos mints on a platform above it. As the ball passed the obstacles, they would tip over with a chance of obstructing its path. My brother wasn’t interested in watching so he went on ahead into the library. Sometimes the Mentos would transform into various figures and jump towards the metal ball in an attempt to catch it.
