We tried to grow ice again today, but couldn’t make it work properly. We used containers to hold our ice cubes in this time, to see if it would make a difference. But it didn’t. The water we used was chilled in the freezer for two and a quarter hours beforehand.
We just can’t replicate the dramatic results we have viewed online.
Any suggestions about what to try next time?

I think I have figured out what we need to change to get this to work. We chilled the water in a freezer compartment (-6*c) rather than a freezer (-18*c) so our water has not been cold enough! Have any of you tried this experiment at home?
