# How does the Contact Angle Measurement Work?

1. The contact angle measurement starts off with project creation as explained in the [How to Create a New Project](https://dropletlab.com/knowledge-doc/how-to-create-a-new-project-in-droplet-lab/) article.
2. While creating the project, make sure that you leave the density differential to its default value since the experiment does not include liquid and liquid.
