can I take cuttings of 'devil's ivy'?

[stripeypillowcase]

thinking of stealing taking a leaf of a plant at a friend's house...

how much stalk do I need? and will it survive 5 hours on the train.

Googling suggests you can propagate from cuttings. To keep it fresh on the train journey, wrap the cut ends in a big wad of wet tissue and then put the whole thing into a plastic bag and tie a know at the top, so it's sealed in its own damp microclimate - this will cut down water loss from the leaves, and mean that the water in the tissues will be enough.
