It was about -4° this evening so I thought I would try some bubbles outside for Tiny Tuesday. I saw some amazing photos on the internet of crystals forming inside bubbles at minus temperatures. It is supposed to be much colder for it to work but thought I would give it a go anyway. I only managed small bubbles as I used the end of a bottle brush as I was too lazy to go upstairs to fetch some wire to make a bigger loop. The smaller bubbles lasted longer, anyway. I did mange a few crystals inside some bubbles but they were slow in forming and the bubbles froze and then cracked. However, it still made interesting photography. The extra is of 2 bubbles sitting on the snow. They were frozen shells, open at the top.
