Make a Sound

The participants form pairs. One of them closes their eyes. The other now produces a short, identical sound at brief intervals, for example "pip pip pip" or "toc toc toc". They move through the room while doing so, perhaps even crouching down or making a sharp turn. The other one has to try to follow them by the sound. The leader naturally has to make sure there are no collisions with others or with objects. It is agreed that the blind player may only move while they hear the sound, and stops immediately as soon as it stops.
