Hot Ice Sculptures – where art, magic, and science meet

Our favorite science experiments are the ones that involve a touch of creativity and a sprinkle of magic. When you mix an acetic acid (vinegar) with sodium bicarbonate (baking soda) they react together to form carbonic acid. The acid instantly breaks into water and carbon dioxide, which creates all the fizzing as it escapes the solution. Once the solution is poured over baking soda it causes a chemical reaction which crystallizes it, allowing you to shape it into form.

Check out the video above for inspiration!

What you need:

  • 4x cups of white vinegar {acetic acid}
  • 4x tablespoons of baking soda {sodium bicarbonate}
  • 1x  pot
  • 1x measuring cup or mason jar {heat safe glass}
  • 1x dish
  • 1x spoon

How to make the hot ice sculptures:

  1. Pour 4 cups of white vinegar into a medium pot, and then add 4 tablespoons of baking soda. Here is the trick! You have to throw the baking soda s-l-ow-l-y, that way the sodium bicarbonate and the vinegar won’t go crazy over the edges of your pot 😉
  2. You have to stir the mix a little and then boil it over low heat.  Once you start seeing little white powdery crystals forming on the sides of the pot you know it’s done!
  3. Store the mix in the fridge for a while (30-45 min is fine) and pour a little bit of sodium acetate powder into the glass dish.
  4. 3,2,1 ACTION! Pour the stored mix over the powder slowly and… the crystal will begin to form!

Kids love to see the hot ice sculpture take shape, so keep pouring the mix into the plate and impressed them with your creative side! You can melt it and do it all over again to create different shapes! How about a swan? A volcano? A dragon? Try adding some drops of food colouring to make it blue, pink, yellow to really take it up a notch!

Do you want to keep surprising them? Touch the ice! Don’t worry, we promise that nothing bad will happen. Do you feel the heat?
