building with coloured ice cubes in the snow
I’m really excited to share today’s activity with you! We were building coloured ice sculptures in the snow!
Now, we’ve played with coloured ice in the snow before, but THIS…
Then a friend in Ottawa shared photos of her boys participating in some Winterlude (winter festival) activities, and they were building some awesome structures with coloured blocks of ice. When I asked her how it was done, I learned that the secret ingredient is…. drum roll please… a bottle of water. I’ll explain in a moment.
First things first:
Gather up your ice cube trays and small food containers and storage containers. I have quite a few of them, and over the course of 2 days, I used them all several times, and made a ton of ice. I would fill up all of the trays and containers with coloured water, and I’d freeze them (some outside over night, and the rest split between the fridge-freezer and our chest freezer) and once frozen, I’d dump them all into a large bin in the chest freezer, and I’d start again. This is about half of my stash. I still have a few trays and a couple of ziplock bags full of cubes reserved for the next time we do this!
but you can use whatever you have on hand. GO EASY on the colour though! For my first round of ice, I put one drop in every ice cube compartment, but I didn’t like how dark the colours were. I kept them, and we used them, but for the next batches, I would mix up a jug of water with 5 or 6 drops of colour in it, and I’d pour that whole jug into a tray or two. Much better.
The perfect conditions:
Once you’ve got enough ice made, you just need to wait for a nice, COLD day! You want it to be BELOW zero (celcius) or below 32 Farnenheit for this to work.
The secret ingredient:
A bottle of water! I can’t believe I hadn’t thought of it before! Every time you add an ice cube to your structure, dribble a bit of water over the cubes, and have the children count to ten. The water freezes quite quickly upon contact with the ice, and while the children are counting, forms a glue to hold the cubes together!
Our temperature was hovering right around zero today, so some cubes took longer than 10 seconds to freeze into place. I think the colder it is, the quicker your water will freeze, and the more solid and sturdy your structure will be.
