Coloured Vinegar with Bicarb - Kids Experiment

When the kids are bored of doing drawing and painting, try this nifty experiment with them. It uses ingredients most people have at home - vinegar and bicarb soda, and is very simple to set up. It kept my daughter entertained for at least an hour!

You will need the following supplies:

• Tray / Large container (I used an old baking tray)
• Bicarb Soda - enough to cover the base of the tray/container
• Vinegar
• Food Colouring
• Eye Droppers or spoons
• Containers to hold the coloured vinegar - I used a muffin tin, ice cube tray would also work well, otherwise any small container.

The method is really easy:

1.  Spread the bicarb on the bottom of the tray

2.  Mix the food colouring with the vinegar

3. Let the kids experiment by adding the vinegar to the bicarb

4. Watch as the vinegar makes the bicarb bubble in mini eruptions.

By the end the tray was a nice brown mess, and my daughter was mixing it all up with her hands!

We did this experiment outside when it was Summer, but it doesn't really make much mess, so would be suitable as an indoors activity as well.
