Freezing Fire

Sam had the idea that he wanted to freeze fire. So this is what we came up with…

We made some cut out flames from thin card and pushed them onto cocktail sticks. We pushed the cocktail sticks into a piece of polystyrene that Sam wanted to include in the experiment. We sat that in a big pot of water, with some food coloring in it for effect. But of course it floated, and we wanted the flames and the polystyrene under the water…

…so we turned it upside down (the flames were now in the water), and put the pot lid on upside down, so that the handle held everything under the water. Then we put the whole thing in the freezer.

Next day we had this.

It was fascinating – some really beautiful patterns had formed in the ice.

We put the whole thing in warm water to loosen it out of the pot.

It looked like a big birthday cake! It was frozen onto the handle which now became a stand.

And here is the frozen fire!

And some details of the ice.

It really was worth taking the time to look at the details in the ice and the patterns which had formed.

Now we started t melt the ice on top

It was in essence a very simple experiment but it really was fascinating to watch how the ice behaved. We really did feel like in our own way we had frozen fire!
