Measuring Mentos ad Coke 🌋 🥤

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:

1. Get all required equipments.
2. Wear safety glasses
3. Pour 20 ml of coke into the 100ml measuring cylinder.
4. Add 5 ml of the detergent in to the 100 ml measuring cylinder with the coke.
5. Add the mentos.
6. Wait for the fizz to happen.
7. 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.
