We love playing outdoors in the winter. Compared to the warmer seasons our winter walks are shorter as is our total time outdoors but we still manage to spend 1-2 hours playing outdoors everyday.
In the winter there are no ‘toys’ in the yard – most break easily in the cold. Of course we still have sticks, pots, and the ultimate loose part – SNOW! I also routinely make various ice blocks for building, collecting and sorting. It is the perfect activity for frigid cold winters.
With the addition of liquid watercolour paint to the water before freezing these blocks add a nice pop of colour to the yard. Sometimes I freeze dozens of trays full of coloured ice cubes and scatter them all over the yard. It is best done just before a snowfall because the children love hunting and digging for ‘gems’.
This year I decided to make some bigger ice blocks using both ice cream pails and square containers. I imagined the children may enjoy using them for stepping stones – they love the slippery spots in the yard. I also figured with bigger blocks they could build bigger structures than they could with small ice blocks. The gross motor skills required for manipulating the large blocks would be a bonus.
The result was unexpected. The combination of the large containers and the above normal January temperatures meant the blocks took longer to freeze – I expected that. What I didn’t expect was that the liquid watercolour would separate from the water during freezing and even disappear completely!
Only four of the ten blocks remained intact when I removed them from the containers. The other ones were fragile because they were hollow! That was certainly unexpected and why it happened I do not know.
The centers of these hollow ice blocks were not wet and any colour that remained was a fine powdery texture. It was like, once the liquid watercolour paint separated from the tap water, the liquid part of the paint evaporated. How that was possible confuses me – the tops of all the blocks are solid thick ice – the bottoms are the thin delicate parts that shatter when touched to reveal the hollow centers.
Well that was unexpected and I still wanted some usable ice blocks so I filled all the containers with water again. I decided to not use any liquid water colour paint this time but I wanted something to make the ice blocks stand out a little in the snow. I found an old bag of potpourri and tossed a few pieces in each bucket. Interestingly, the next day the water had turned a nice shade of red,
However, after four days outside, in the shade, in January, there is only a thin partial layer of ice on the surface of each bucket of water. How is it possible that in Manitoba I cannot freeze water outside in January?
That is unexpected.
