• a second member comprising
• a second chamber operable to contain a second ingredient, the second member defining the second chamber;
• a sealing member sealing the second chamber,
• an extension member extending through a central aperture to the first chamber, the extension member including a passage defined therein, the passage at least partially defining the second chamber,
• a mixing device coupled to the extension member and disposed within the first chamber, the mixing device movably disposed within the first chamber;
