iPhone 7's slo-mo mode

The newer iPhones have this "slo-mo" mode, which is basically very fast video (240fps) that you can then tag a certain section to have it played back slowly.

On recent trips I managed to capture some interesting footage, for example: some seagulls that flock around the ferry in Helsinki harbour, on the way to Suomenlinna Island:

Or leaping dolphins at the National Aquarium in Baltimore: (note that we had been going here everyday for almost a week, which is why I got relatively good at anticipating when they do neat tricks. What I enjoyed about this aquarium is that they don't just make the dolphins do crowd-pleaser tricks, but take time to explain the kind of interactions and trainings they do to keep them healthy. Keeping marine mammals in captivity is a controversial subject...

Kinda cheesy, but pretty neat for the first while at least...
