What causes this?

Just got a new (older) Lava lamp. 

I love the size and the psychedelic blue, but now that I've turned it on, the goo has spots on it. 

See the pics.  Is there anything I can do?

Fluid bubbles in the wax.  It's not abnormal, but most of us here don't like that.  Sadly there has not been a consistent solution for it.  Sometimes it can happen if a lamp hasn't been used for a while, so running it regularly may help.  Then again sometimes it happens because a lamp is ran too much.  It's one of those individualities that give each lamp it's own character.  Hopefully it will resolve with use, at least to the point where it doesn't bother you.

Thanks for all your help today! Very much appreciated.  I'm going to see if it goes away.
