May 3

Today Ray and I heated the mixture for an hour. Specifically, we first put the mixture on a hot plate and stirred it while it was heating. Then we move the heated mixture to the bunsen burner until it came to a boil. While, the mixture was boiling we added 10 ml of oleic acid. We kept the mixture boiling until it smelt like ammonium. Once it started to smell we then cooled it and cover it until tomorrow.   Tomorrow, May 4 ray and I will add kerosene and finish our ferrofluid. Later at night during study hall, Ray and I went to see our future ferrofluid and it was broken up into 3 layers.
