Science Week – Experiments

We carried out some more experiments today.

They both involve chemical reactions. First we put ‘Mentos’ sweets into a bottle of ‘Coke’. It caused the Coke to gush out of the bottle.

Then we put baking soda into a balloon. We put the balloon over a bottle containing vinegar. When the baking soda is tipped into the vinegar a gas is released which fills the balloon.
