It's hot and you still have another few hours on the road. The kids are starting to fidget and have already grown tired of Minecraft: Pocket Edition on their iPads. What to do? Well, if you're a Sky subscriber, there's always Sky Kids. The child-centric streaming app launched in March and is getting a handy new feature today -- offline playback. So before you set off in the car, you can download a bunch of episodes (or seasons) to keep them entertained. The catch? You'll need a Sky Go Extra or Sky Multiscreen account. Otherwise, you're still reliant on Wi-Fi, 3G and 4G streaming.
