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)
2. Place the beaker ion the sink and add a mentos.

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
Coke	48
crushed mentos	00
Coke Zero	44cm
75 Degrees
45 Degrees
30 Degrees
15 Degrees

More investigations:

1. Does it work better with hot Coke( group) , warm Coke ( group) or cold Coke?( group)
2. Use Diet , Normal and Coke zero.
3. Does crushed Mentos work better than whole Mentos?( group) 

1. Add 50 ml of cold diet coke to a beaker
2. Add 5 mentos.

150 MLS of Tap water 

2 Beakers

Bunsen Burner

 Bunsen Burner Tripod

Heat proof mat

Gauze mat

Thermometer

Method:

4. Add salt to one beaker and mix.
5. Place the beaker with tap water on the tripod.
6. Place the Bunsen Burner on the heat mat underneath.
7. Light the Bunsen Burner and adjust the flame to blue.
8. As it heats up place the thermometer in the beaker of water until it is boiling.
9. Record The Temperature on your blog.

10. Repeat the process for salt water.
