Ice Bubble

Finally...almost cold enough to try this out.. not perfect..needs to be a lot colder.. Ice Bubble.. Ideally needing minus 4'C, this was at minus 2'C . bubble was blown onto cold surface (my car) lit by the early morning rising sun.. slightly thicker bubble solution seems to work better than the standard kids solution - i added washing up liquid.. I think a better or cleaner solution might give better results without the residue dots on the bubble.
