Its a gelatine powder you mix with a shake, it turns out a bit like angel delight... not wanting to dissapoint though its not exactly like angel delight, but its passable.
To make its best if you mix the mousse powder with the shake powder and then add it to the water, blend for at least a minute, then allow to set for 10 mins or so.
Could be worth a shot surely? you are only supposed to use it once a day, but at least if it worked for you, 1 mousse and 1 bar only leaves 2 packs to worry about!
heres a link to ebay, todays not a good day there is usually more mix a mousse on, and the ones I bought had free postage,
