Coke and Mentos

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.

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)

Findings:

Add your measurements to the table

Liquid	Height

Crushed mentos
Coke zero	Nothing
75 Degrees
45 Degrees
30 Degrees
15 Degrees

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)
