Hi everyone! My first post, so bear with me. I have a query that I didn't quite know who to ask about, and came across this site, so I hope this is the right place to put it. My cat's bowl was left (empty) on the verandah and got caught in the rain yesterday afternoon. Overnight temperatures dropped to below freezing, but not much: I would guess to about -2 C, as it was just below -1 when I got up at seven o'clock. When daylight broke (and I could see the bowl) I noticed a strange sundial-shaped ice formation, and this is what has me flummoxed. I was so baffled that I took it in and stuck it in the freezer so I would have time to take some pictures. What on earth could have caused it? I have pondered this all day... a hair? ...a spider web? I cannot see anything inside the spike: it looks as if something jumped in or out of the water as it was freezing, but am well enough informed to realise that it would have to be a lot colder for that to happen, if it would be at all possible. Since I am new to this I hope my attached pictures will upload properly, if they don't I will try again. I am grateful for any insights. Bye for now!
