'Rescuing' Paper Clay

[crossmirage]

I bought a pack of lightweight, 'soft' paper clay (pictured below) some time ago, never got around to using it, and it hardened up. It's not bone-dry yet, so I'm wondering if there's any way to re-wet and make it all nice and fluffy and malleable again. I don't want to let it go to waste since it's pretty good and fun to use. Any suggestions?

Spray it with water; if that doesn't work, it's best to just buy some more. Good thing paper clay is cheap.
