Science Experiment

For the letter f, we made fizzing foam!  This is a popular science experiment because it is so colourful and visual.  We needed food colouring, baking soda and white vinegar.

We put a few drops of food colouring in the bottom of clear cups.

Next we dropped in a few teaspoons of baking soda.

Lastly we poured some white vinegar into the cups.

Straight away, we could hear the fizzing sound as the mixture changed and reacted by overflowing!
