Karen,

Plant or animal cell vacuole?

If a plant cell vacuole is the idea then think about turgor pressure and
maintaining the strength of the plant cell.  Could you wear something which
would inflate and deflate.  The vacuole in the plant is to help maintain the
integrity of the cell and needs to be capable of responding to changes in
heat, or ion concentrations.

If you are thinking of an animal cell then the idea would be different.  Try
thinking along the lines of temporary storage and transport.  Maybe have a
cut out circle of cardboard upon which you could have different sliding
levers that could represent molecules moving in and out of the vacuole.

Hope this helps.
