Things you've always never wanted to know
The largest liquid body on Earth is the outer core. The inner core is solid iron-nickel and measures around 758 miles across. This is surrounded by the 1,403-mile thick liquid outer core. The outer core has a total volume of about 1.7 x 1020 meters cubed. It represents around 29.3 percent of the Earth's mass and 16 percent of the Earth's volume, or 100 times the volume of water in Earth's oceans.

The substance was originally created to test the power of deodorizing products.
