Using 2 Colour-Coded Spill-Proof Drinking Bottle with Detachable Condensation Tray for Matchocoffee (flavonoids) and for RED wine (lycopene), my daily fluid intake for most days can be totally controlled. However, hot beverages would deform and melt plastic containers made of polyethylene terephthalate (PET).
For effective mixing of Matchocoffee: Anti-Oxidant Zero-Waste Drink Mix (flavonoids), the beverage is shaken, not stirred. Vigorous shaking does not result in any leakage if the liquid is at room temperature (> ~293 K). However, leakage occurs when temperature of the liquid is lower (< ~283 K). Here is the Dynamic viscosity of dihydrogen monoxide (H2O) as a function of temperature.
