Mentos and coke explosion

LO-Be able to follow a method to create a a coke explosion and be able to find out which type of coke creates a bigger explosion

What you need:
Coke,Mentos And an open space

Method:
1.Collect what you need
2.Go outside in the middle of an abandoned field
3.Carefully open the bottle of diet soda.
4.Position the bottle on the ground so that i will not tip over.
5.Lets start with seven mentos for our first attempt
6.Then drop the mentos

Evaluation:
No the geyer did not did what we expected its an inch high
I think its the diet coke did two inches height
Kind off we need more satisfaction from the geyser.
We need to shake the bottle first then put the mentos on

Exploding foam science (Requirements)

You will need (equipments)
We will have 4 groups of 5 students.Each group will need the following
-A clean 16 ounce plastic soda bottle
-1/2 cup 20-volume hydrogen peroxide liquid (20-volume is a 6% solution)
-1 tablespoon (one pocket) of dry yeast
-3 tablespoon of warm water
-Liquid dishwashing soap
-Food colouring
-Small cups
-Safety goggles

What to do
Step 1-Collect Equipments  and take it outside on the grass

Step 3-Add 8 drops of your favourite food colouring into the bottle
