Floating droplets: how droplets can 'levitate' on liquid surfaces

1. What if 2 liquids don't mix

1.1. levitation due Tmeperature defference

1.1.1. E.G. cream in our morning coffee

1.2. Guide for droplet based designs

1.2.1. E.G. in microfludic chips

2. Inside a single drop

2.1. 2/3 relationship between time of levitation and Temperature difference between 2 fluids

3. An uplifting experience

3.1. tiny box filled with silicone oil on hot/cold plate

3.1.1. pumping silicone oil droplets while changing plate temperature

4. A cushion's character

4.1. how bigger the temperature difference, the stronger the pressure pushes against the droplet's is

4.1.1. preventing it from sinking and making contact with the bath.
