Properties of Materials

Charles Macintosh was a Scottish chemist and inventor who is best known for his invention of the waterproof fabric that came to be known as “Mackintosh” or “Mac”.

In 1823, he discovered that a solution of rubber in a solvent called naphtha could be used to coat cloth, creating a waterproof material that was both lightweight and flexible.

Today, Toucans investigates whether materials were absorbant / waterproof. Toucans were very good scientist. They had to use their skills in communicating findings and ensure they were conducting a comparative test.
