How Do I Get Java Moss To Float? Keeps Sinking.

[totally tropical]

Firstly apologies for my numpty question.

I have a large segment already settled which was orinally tied to driftwood, now I would like to use a separate clump as a floating plant which apparently it can do - it will come in handy for fry to hide.

Anyhow, I have tied a separate clump together it so that it does not break free and it slowly sinks, I have tried to thin it out, but again it sinks.

I am assuming that it needs to be attached to something at the top - not sure what to attach to if this is the case.

Any ideas? - many thanks.
