‘One of my favourite science-based apps...The Elements in Action is easy to navigate and attractively designed.’
– The New York Times

The periodic table comes to life with 79 video explorations of the weird, wonderful, and sometimes alarming properties of the elements. Filmed by BAFTA award winner Max Whitby in partnership with Theodore Gray, author of the iconic book and app The Elements, and previously available only in a few museum installations, this is the most beautifully filmed collection videos ever assembled to explore and explain what makes each element unique and fascinating.

What happens when highly reactive rubidium is dropped into water? Or when a cannonball is placed in a pool of mercury? The Elements in Action shows you one definitive demonstration for (almost) every element, ranging from the bizarre to the sublime, all assembled in one place for you to view in the comfort and safety of your iPad, with very little danger of death by fire, dismemberment, or poisoning.

The Elements in Action works as a stand-alone app, but really shines when combined with the original app, The Elements: A Visual Exploration. Installed together, the two apps find each other and link together, allowing you to flip seamlessly between viewing the elements as objects of contemplation in the original, and objects of dynamic action in the second.

Touch Press is the publisher of twenty of the most widely admired apps in the world, including the original Elements app, a milestone in digital publishing, as well as Barefoot World Atlas, selected by Apple as one of the ten best apps ever created in the history of the App Store, and Disney Animated, the definitive living story of Disney animated movies.

Good overall

Interesting app worth the money overall. I do think it could do with some more features though, like an actual periodic table (the one in the app isn't true to scale) and the ability to enlarge the static pictures of the elements that rotate in the top corner. It's clearly a polished app but I was disappointed by some of the videos, which looked quite amateur.

Finally, anyone expecting the videos to show chemical reactions will be disappointed. A few show reactions but most are just videos of cutting the metal with pliers, or using a meter to test radioactivity. None of the videos for the most reactive metals, like caesium and francium, show reactions.

Still not up to date.

New element names not included still.

Nice app

Anyone complaining about the lack of videos (there are 72), only 92 of the elements in the periodic table are found in nature. And so the missing elements are either inert and therefore boring, radioactive and dangerous, or man-made and incredibly expensive. I suspect the missing elements wouldn’t make for very interesting videos.
