Modify the formula of Raphaello

There are two possibilities, either you let Raphaello experiment with his recipe or you discreetly substitute his ingredients with your own. The weak point of the latter solution is it doesn't allow the desired response but it permits you to avoid catastrophe. After having placed your version of the concoction in the well, you wait a few seconds, then a few minutes. After almost an hour, several golden bubbles break the surface then the calm returns.
