Aim:

To make it fizz up.

You will need:

a clear plastic cup contianing bicarbonate of soda, 3 sultanas, a mixing stick, warm water and a small amount of vinegar.

Method:

1. Pour warm water into the bicarbonate of soda.

2. Then put sultanas in.

3. Add vinegar.

Prediction:

It might fizz up and explode all over the table and then the sultanas dissolve.

Observation:

The sultanas start bopping up and down. It is really exciting because the gas bubbles are pushing them up.
