Drinks And Mentos Lab Report

Why does fizzy drinks react to mentos the way they do and what drink will create the most significant reaction?

Introduction
Have you ever seen what happens when you put Mentos in fizzy?
Did you ever wonder what caused this reaction?
Well today that's what we are doing, the point of our experiment is to find out what and how the reaction is caused and what fizzy drink will cause the biggest reaction

Aim.
We aim to find out which of our three carbonated drinks (Diet Coke, Fanta, and Sprite) can cause the biggest reaction (in terms of height) when we add ‘mentos’ to them.

Hypotheses\ prediction.
We think that Diet Coke is going to create the biggest reaction, and therefore the greatest height, because it’s more carbonated than Sprite and

Diet Coke, Fanta and Sprite (all 1.5L)
4 packs of mint Mentos (14 per pack)
2 metre measuring tape
Tape
Recording device
Safety glasses
Safety coat

Method
Put on eye protection goggles and a science lab coat
Set up and start recording the experiment on the camera
Place the bottle of Cola in a flat outdoor area, at least two metres from any buildings or anything hanging above the area
Carefully remove the cap and get the pack of mentos and make sure it lines up with the top of the bottle and squeeze them out carefully but still fast
Run back without tipping the bottle over or disturbing the reaction.
Record the maximum height of the reaction in the results table
Repeat the experiment so each different fizzy has 3 sets of results.

Research

A drink like diet coke or Fanta is packed full of dissolved carbon dioxide gas, which in turn forms bonds with water. While the soda is in the bottle, the gas is kept in solution by the bottle's design, which was made to pressurise the gas.

When you pour some soda into a glass, some gas escapes and that’s what makes the foamy bit at the top, but most stays trapped by the surface tension of the water. But all those gas bubbles want to escape, no wonder that soda makes you
