HEllo everyone.
This week in Science, Chemistry we are trying to experiment with coke and mentos. Here is what we are working on.
Aim: I want to find out how many bubble are made when mentos is dropped in coke.
Method:
Equipment:
- Coke, Coke Zero, Sprite
- Mentos
- Measuring cylinder, 100 ml & 10 ml
- Small beaker
- Safety Glasses
- Liquid Soap/Detergent
Instructions:
- Get all required equipments.
- Wear safety glasses
- Pour 20 ml of coke into the 100ml measuring cylinder.
- Add 5 ml of the detergent in to the 100 ml measuring cylinder with the coke.
- Add the mentos.
- Wait for the fizz to happen.
- Measure the height of where the bubbles end up.
Results:
| Coke | Coke Zero | Sprite |
Height of bubbles | 45 mL | 35 mL | 40 mL |
Conclusion
I found out that if you add detergent to the mentos and coke experiment the bubbles stay on its same place.
I also found out that the sprite is more effective than coke and coke zero even though coke was the highest because we didn't add the equal amount of each fizzy.
