Coke and Mentos

Coke and Mentos

Aim: To see if coke explodes when a Mentos lolly is dropped into it using different temperatures and different kinds of coke.

Hypothesis:  I think the Diet coke will be better becaus it has less sugar 

Steve Spangler Mentos & Coke Experiment

We can do better: We need to try several experiements to see which one works best

Equipment:

Ruler

Beaker

Thermometer

Coke Mentos

Measuring flask

Method:

Stage 1: ( All groups)

1. Add 150ml of coke to a measuring flask
2. Place the flask in the sink.
3. Drop in 1 mentos a watch the effect.

Stage 2: 

Group 1
Test 1

1. Heat up 50ml in a beaker of coke ( Using a thermometer heat it to 75 degrees)
2. Place the beaker ion the sink and add a mentos.

Test 2

1. Add 50 ml of cold diet coke to a beaker
2. Add 5 mentos.
3. Record the hieght it reachs

Group 2
Test 1

1. Heat up 50ml in a beaker of coke ( Using a thermometer heat it to 45 degrees)
2. Place the beaker ion the sink and add a mentos.

Test 2

1. Add 50 ml of cold diet coke to a beaker
2. Add 5 mentos.
3. Record the hieght it reach

Group 3
Test 1

1. Heat up 50ml in a beaker of coke ( Using a thermometer heat it to 30 degrees)

Test 2

Group 4
Test 1

1. Heat up 50ml in a beaker of coke ( Using a thermometer heat it to 15 degrees)
2. Place the beaker ion the sink and add a mentos.

Test 2

1. Add 50 ml of cold diet coke to a beaker
2. Add 5 mentos.
3. Record the height it reach

Findings:

6 mentors lollies where dropped it a bottle of coke. The height of the fountain of coke measured in centimetres. A mentors was crunched and we we dropped into  the coke. this shows no result.

Add your measurements to the table

Liquid	Height

crushed mentos	00
Coke Zero	44cm
