Scattering of facts
Good presentation to introduce the scale of structures and organelles in bone, though sometimes a jump of 100x is hard to follow. Could do with better explanations of the links between each thing you see. Introducing "mitosis" in several cells but not attempting to explain this concept, or the different stages of it which you see, is unhelpful. Best used with the device flat: vertical orientation makes screens scroll by too quickly. Navigation is quirky and inconsistent, but by the time you've finished exploring every corner (about 20-30 minutes) you'll have got the hang of it. The background music is the first option you'll turn off.
