roly poly bottle / Bottle

Normally, 1.5~2 liter water bottles are used in most houses. However, children, women, elders sometimes have trouble with using these big bottles since they do not have enough strength. They sometimes end up spilling water to the table from the bottles slipped from their hands.
This bottle suggests a solution in an easy way. It contains a centroid at the bottom as a roly poly do. Children can use the bottle tilted by a finger.
Also, the mouth of the bottle is located lower than normal bottles so that people can target for cups more easily. Since the end of the bottle is flat,
people can stand it like a normal bottle or put it face down.
