This is underwater footage of an outside swimming pool. During the day the electric water fountains were switched on, which as you can hear from the audio, gave the usually serene pool a menacing edge. Because of this, I chose not to swim in here during the day, but waited till night-time (and the potential wrath of the security guard) to swim in peace. I tried also to get underneath the pool, to record the EM noise from the heating system but was allowed access.
