1) 4 cups that were same size and same shape.
2) Put 2oz (1/4 cup) of water in each of the 2 cups.
3) (AGAIN!) Put 2oz (1/4 cup) of acetone in each of the 2 cups.
4) Put 0.5cm of oil into one of the water cups and 0.5cm into one of the acetone cups.
5) (REPEATING!) Put 0.5cm of aqueous into one of the water cups and 0.5cm into one of the acetone cups.
