- if you want to grow a big crystal its important to separate the one that you like the most from the others and put it into a fresh prepared solution that is cold | - if you want to grow a big crystal its important to separate the one that you like the most from the others and put it into a fresh prepared solution that is cold | ||

If you are a bit patient you can see the crystal growth. | |||
The salt molecules form straight lines and form solid patterns that remind of an icy surface. | |||
Some of the footage that I shot while observing crystaline structures and crystal growth under a microscope was used for a the fulldome-project | |||
