Claim:
A method of mixing a first substance that is contained within a container with a second substance that is contained within a first sub-container that is rigidly attached to the container and is contained within the container and with a third substance that is contained within a second sub-container that is rigidly attached to the container and is contained within the container, the method comprising: opening a first seal of the first sub-container responsive to opening a seal of the container, by pulling on a first tether that is attached to the seal of the container and to the first seal of the first sub-container, without opening a second seal of the second sub-container that is attached to the seal of the container by a second tether that is longer than the first tether; and opening the second seal of the second sub-container in response to pulling the seal of the container that was opened, to cause the second tether that is longer than the first tether to open the second seal of the second sub-container.
