Recycling oil:
To recycle oil we dicided to make soap. We took 20 ml of oil and we filtered it. Then we put 4 g of hidroxium of sodium in a erlenmeyer with destilled water. Then we mixted the filtred oil with powder soap, hand soap and flour. This mixture we atted to the destilled water and hidroxium of sodium. Finally we waited for a week.
