Exploding coke

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

Hypothesis: 

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.

Group 1  ( Levi)

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  ( Tehya)

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  (Lars)

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

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

Group 4  (Jaz)

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

Group 5 (Rinieya)

Test 1

1. Heat up 50ml in a beaker of coke 
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:

Add your measurements to the table

Liquid	Height
Coke
Crushed mentos
Coke zero	Didn't explode
75 Degrees
45 Degrees
30 Degrees	Best time to do it
15 Degrees	Didn't explode

More investigations:

1. Does it work better with hot Coke( group 1) , warm Coke ( group 2 ) or cold Coke?( group 3)
2. Use Normal and Coke zero.
3. Does crushed Mentos work better than whole Mentos?( group 4)
