A child blows soap bubbles You can see how the lipid membranes around the cell and around the vacuoles seal themselves off using soap bubbles. Soap bubbles are a kind of lipid membrane. They're not exactly the same as cell membranes, but they're made of fat molecules and they act the same way. [...]
