This document describes a game called "Vertical Dunk" that can be played by astronauts in microgravity. The game involves dividing into teams and taking turns trying to throw or hit a ball through a net stretched across a corridor. If a player is successful, they can switch someone from the opposing team to their team. The game aims to provide social and physical interaction without specialized equipment and helps exercise muscles, develop strategy skills, and improve personal relationships through light physical contact.
