Abstract: A system includes a plastic or glass of a substantially cylindrical container includes a first liquid. A flexible sleeve about a lower area about the container including a surface of a bottom upon the sleeve and an upper of the sleeve defines a substantially middle of a circular surface including a substantial segment of the sleeve. A flask generates an integration of a substantially cylindrical structure of a hollow curvature including a top and lower end. An inner side against a structure of a thin element about the sleeve urged against the system of a second liquid in with left to right contact to the thin element surface of the sleeve, and through the cylindrical structure of the thin element structure.
