Ice marbles

I came across this on Facebook last month and thought it'd be cool to try if we get a cold winter like two years ago.

Given we've had a bit of a cold snap now for two weeks, the kids put two balloons out just to give it a go. Despite it having been around -4°C every morning when I left for school they hadn't completely frozen. Then yesterday it was -8°C in the morning, so finally our balloons were ready. Unfortunately it hasn't snowed yet so they didn't look quite as impressive against the grass as they would have on snow but they are striking enough that we'll definitely make a bigger batch next time we get snow!
