• a tube having a filling end and a closed dispensing end, the closed dispensing end including an aperture through which the mixture of ingredients is dispensed, in use;
• a first plunger in the tube sealing the filling end;
• a second plunger in the tube between the dispensing end and the first plunger, the second plunger including a breakable membrane portion;
• and
• a mixing apparatus, including
• an elongate shaft having a pointed end and a driving end,
• a foldable set of flanges configured to be attached to the pointed end of the shaft, and
• wherein a first cavity is defined between the dispensing end and the second plunger for holding a first ingredient, and wherein a second cavity is defined between the first plunger and the second plunger for holding a second ingredient,
• and wherein the foldable set of flanges has a width less than a diameter of the aperture when in a folded position, and wherein the foldable set of flanges is biased in an unfolded position, and wherein the pointed end of the shaft is configured to pierce the breakable membrane portion when the mixing apparatus is inserted into the tube through the aperture.
