We've been having quite mild weather, so yesterday was the only day that I could produce a reasonably-sized ice lantern. I put it on the edge of the pond and lit it when it got darker. The fleetingness of it appeals to me -- and it looks pretty nice too!
At the start. The structure of the ice adds to the appeal of the latern, I think.
Later on. You can see the top of the latern has already melted away.
I can't wait for it to start freezing again. If it gets consistently freezing again, I might do some experiments with different layers with watercolors in 'em, just to see how that would work out.
