Dear Mr.Wood,

If crystals can form in the lave lake, then would they just float on top of the lava lake or would they slowly sink and then suddenly get blown out of the volcano in the erruption? Please answer my question soon! Hope you had a great Thanksgiving over in Antarctica!

                 Sincerely,

 (p.s. hope you can get pictures of a penguin!)

Good Idea!  The theory is that they do float and sink and repeat that process which allows them to grow to a larger size.  Then they get blown out of the crater already formed to a large degree.I had a very nice Thanksgiving,  thank you.  
Cheers,
Mr. Wood
