Non sapevo dove batterlo e l'ho messo qui:
The purpose of this experiment is to investigate how different natural products can affect the tensile strength and elasticity of our hair. Eight substances, ranging from honey to olive oil, were used to soak the hair for 24 hours. The outcome of the preliminary experimental runs indicate that honey and egg could be beneficial to hair, while kiwi puree had quite a significantly negative effect. Our hypothesis that the proteolytic enzymes can damage our hair is thus supported by the kiwi data. Our further investigation revealed that saccharine doesn't appear to be the hair-strengthening component in honey, and we hypothesize that it's the water-trapping network, much like the extracellular matrix, that constitutes the fortifying agent. Also, both our tensile strength and elasticity tests indicate that isopropyl alcohol has unusually positive effects on hair, while commercial beer does not. While this difference may be largely due to the difference in concentration, the chemical structure of the alcohol (isopropyl alcohol vs. ethanol) may also be another cause in the difference.
