To create a DIY liquid pen at home, you will need a small container, water, food coloring or ink, a small brush or cotton swab, and a pen or marker. Fill the container with water and add a few drops of food coloring or ink to create the desired color. Use the brush or cotton swab to soak up the colored liquid and carefully transfer it into the pen or marker. Allow the pen to sit for a few minutes to absorb the liquid before using it.

A pen can be considered a lever because it has a pivot point (fulcrum) where you hold it, a point where force is applied (effort) when writing, and a point where the pen contacts the paper to create the writing action (load). By applying force at one end (effort), the pen's design allows it to create a writing action at the other end (load), making it function like a simple lever.
