Experiments are the volcano! #science

Little Missy loves doing experiments. The Doen dit self Wetenskap (Do-it-yourself Science , Priddy Books) experiment book is used on a daily basis. We bought it for cheap at Reader's Warehouse.

The only way we can get away with not doing an experiment is by explaining that we do not have all the "ingredients".

I had to go and buy food colours for another experiment, so Dad did not have an excuse any more for this experiment. She has been eyeing the volcano for a long time.

Baking soda and vinegar...

The volcano!

Happy Scientist! It worked!
If you are ever stuck with nothing to do for bored children. There are hundreds of Pinterest pins for Science experiments. You don't even need to buy a book.

How to blow up a balloon without blowing into it #science


Hubby bought a science book for Little Missy, and she has been enthralled by all the easy experiments! We are constantly bugged to do another one!

This is great for the winter holidays when you want to do something of value with your little ones.

The recipe is easy:

Ingredients:
Balloon
Plastic bottle
Vinegar
Sodium bicarbonate / baking-soda

1. Pour vinegar into eighth of bottle.
2. Pull balloon over a funnel, and drop one and half teaspoon of sodium bicarbonate into it.
3. Pull balloon over opening of bottle, preventing the bicarbonate from spilling into bottle before it is secured onto the bottle.
4. Hold the bottle securely when pulling up the balloon to dump the sodium bicarbonate into the bottle.
5. Carbonic acid gas is released which makes the balloon blows up.

It really works!
