Coke Volcano

What we did: an experiment that room 12 did to see a similar reaction to a real volcano that is erupting and what it could be like.

Why we did it: to see a similar result of what a volcano would do if you were in one.

How to do the experiment: you need a 1.5 or 2 litre of coke and mint flavoured mentos. First make sure the coke bottle is secure. Then get the mentos ready so it falls into the bottle fast. When you're ready put the mentos in you will probably need 8 of the mentos out of the packet  Once you put the mentos in the bottle stand about 3 feet back.After a few seconds the coke volcano will erupt.

How it worked: when you put mentos in the coke it the makes the carbon dioxide rise
from the coke to make an explosion with a chemical reaction. The coke and gas in the bottle were like the magma in the magma chamber, and the neck of the bottle was like a volcano vent which is narrow. It exploded like a geyser.

How it was similar to a volcano: when you put mentos in the coke it's like the pressure from the volcano then the fizzy makes it erupt. The smaller the valve or vent, the bigger the explosion

We learnt what a volcano could look like when it erupts. The smaller the vent the bigger and higher the eruption.

  1. This looks like a wow experiment you could do at home with different-size vents. May be this is a good experiment to do and then send the photo to Mr Liley?

    That coke video was so cool that the coke went so high and fizzed up about 1 meter high. The explosion was so cool it looked like a real volcano.

  9. I really did like the experiment we did was awesome the coca cola fizzed up really high and the coca cola reacted to the mentos we could try the experiment by using different flavors of mints.
