Fizzy Colours Experiment
Would you like too see your colours bubble?
Well, then here we are with a new kitchen science activity.
Let us see how can we make it.
Things you need
- 4 table spoons of baking soda
- A cup of vinegar (white)
- Four different food colours of you’re choice
- A muffin tin
How to do it?
- Firstly it is suggested that you carry out this activity in your backyard or in a open space. It is because this experiment may spill over. keep things ready on a table.
- Fill muffin cups half with vinegar. Now, add the colours in those cups. Add a teaspoon of baking soda, and step behind. You can see that your colours will start too fizz.
Why does it happen?
- This happens due to acidic reactions. Vinegar has acetic acid which reacts with the sodium bicarbonate of the baking soda to form carbonic acid.
- Baking soda contains sodium bicarbonate
- Vinegar contains acetic acid.
- Carbonic acid becomes unstable and immediately splits into two components; Carbon dioxide and water.
- Vinegar + baking soda = Carbonic acid = Carbon dioxide + water.
- The carbon dioxide bubbles up but as it is heavier than air, it starts to flow like water over the edge of the muffin tin.
- Enjoy the bubbly colours coming out from the muffin caps!
