Learning objectives |
The purpose is to learn how to make homemade soap |
|
Description |
Participants are divided into fifteen groups of two-three people. Each group was given two bowls, one with 750g of recycled olive oil and the other one with 102 g of sodium hidroxide. This sodium must be dissolved into water. First of all, participants had to mix up the sodium with the water carefully. The solution must be slow so as not to produce vapour. Then, after letting the solution rest for some minutes, which is called caustic soda, this mix is added to the recycled oil stirring quickly, but pouring the soda very slowly. At that moment, the mixture turns into soap. This reaction, although it is practically instant, won’t be completed until the components have been mixed up very well. Once this is achieved, the resulting modelling clay is placed in moulds and wait for a month to be used as the solidification is a very slow process. to give scent, some essences and food flavourings were added. |
