If you find yourself at a family gathering with bored children over the holidays, allow us to recommend an activity that can keep kids engaged. Figure out something the kids can do that involves motion—knocking down a tower of blocks, rolling a ball or toy car down stairs, even just making silly faces—and record them using the Slo-Mo option in the Camera app. Swipe left (iPhone) or down (iPad) on the viewfinder or labels to move from Photo mode to Slo-Mo mode, and then tap the red record button to start filming. Our test kids had fun building tall towers to knock over while filming, giggled madly while watching the videos, and went on to brainstorm other activities to film in slow motion.
