We hold these truths to be self evident; if you carry an umbrella, it will not rain, if a clean nappy and wipes are in your handbag, none will be required, and apparently, if you try to make ice mobiles, the weather will suddenly warm up.
Yes, that's right, we are currently enjoying a sub-tropical heatwave of 2 degrees celsius. Not exactly time to break out Bermuda shorts, but warm enough to foil my well laid plans of ice-based tree decorations.
Thankfully, I have a freezer so the children's foraging efforts did not go to waste and dangling from our cherry tree is a triple ice mobile with rose hips preserved in frozen form (oh, and some glitter, because there's always room for a little bling).
To make them we used some foil cases leftover from mince pie munching into which the children placed some small, scavenged objects they found on a walk yesterday. Then I laid a piece of string across the line of cases, making sure it dipped into the centre of each, and filled the three cases to the brim with water. Finally we left them outside overnight... only to find them still liquid this morning.
I am beginning to think that if people in all areas of the country tried to make ice mobiles, we would immediately create a nationwide thaw. Sod's law is a powerful thing.
