<p>A sturdy, reusable double-layered plastic bottle to be used for filling with two separated liquids. The larger inner-layer can be filled with water, and the outer-layer can be filled with cordial/squash. There will be a manual pump at the base of the bottle to pump cordial from the outer layer into the inner-layer, mixing the liquids to a desired proportion. The bottle will have two openings; a large flat lid (to allow it to stand on its head) which corresponds to the inner cavity, and a large removable base to fill the outer. Valves will be used within the mixture system to enable the liquid to flow.</p> |
