We have all used 5 or 7 litre water bottles. It is quite inconvenient to pour water out of them, especially for smaller children. The idea would be creating football shaped base for attaching water bottle into it. Bottle would be placed on to base upside down that allows water to flow out due to gravity. Tap can be used for controlling water-flow. In additional cooling system can be added to make water nicely cool.
