So the superhydrophobic coating and the hydrophilic coating both arrived on Friday, and we worked on finishing the leaves today.

A quick update on the leaves, here's how they are made:

1. laser cut a piece of wood to the correct shape

2. cover the piece with a layer of tin foil (must be very very smooth)

3. spray paint the leaf with hydrophobic paint

4. Use the previous method to make grids of hydrophilic paint on the leaf

With this method, we made 3 leaves that are ready to be tested tonight.
