Elephant toothpaste per cubic meter

[alewisGB]

what is the best formula for elephants toothpaste not using yeast using potassium iodine and hydrogen-peroxide(30%) and of course soap.
how much reactants would i need to fill let's say... 100m cubed (im not going to do that much but its easier to work with)
* how long would the reaction take?
* what would be the safety limits of reactants and precautions?
* how much heat will it produce?
* is it illegal in the UK?

Start with the reaction equation.

im not a chemist I am more of a physician?

This is not difficult. Reaction that is responsible for the observed effect is hydrogen peroxide decomposition. You know volume of oxygen, calculate how many moles it is, use decomposition reaction to calculate how many moles of hydrogen peroxide you need.

You should be able to google details.
