Sure! To measure the remaining daylight with your hand, follow these steps:

1. **Stand facing the sun:** Make sure you have a clear view of the horizon where the sun is setting.
   
2. **Extend your hand:** Stretch your arm out fully in front of you with your palm facing you. Keep your fingers together and horizontal.

3. **Align your hand with the horizon:** Place your pinky finger on the horizon line.

4. **Count the number of fingers to the sun:** Count how many finger widths fit between the horizon and the bottom of the sun. Each finger width represents approximately 15 minutes of daylight remaining.

This is a rough estimation but can be quite handy when you're outdoors and need to gauge how much time you have before sunset!
