Abstract: Two bottles of any size, shape, color or texture one with a regular size spout, another with a much greater opening or any combination of the two. The concave bottom with a cap like grooved stopper within of the first bottle would allow the second bottles neck like structure to penetrate and twist itself tight into the first bottles bottom therefore creating only one bottle with two separate chambers. Allowing you to place any combination of liquid or solid matter like; soda, candy, soup and bread, detergent and fabric softener, oil and coolant, toys, t-shirts, trinkets etc.
