In the new two and a half minute video, the teacher of a school group abandons his homework to learn about gravitation and to prepare a presentation. They use the power of the new iPad of course. The students hold on to numerous experiments with the 8-megapixel camera. From falling melons to bicycle jumps to the simulation of weightlessness, all sorts of things are on offer here. Because everyone in the group has an iPad, they can quickly and easily collaborate and share their results.
