Makeshift Level

This is my makeshift level, made from scraps around that had no purpose, however through inginuity and hard work I gave them a new purpose as a working level, to ensure that surfaces are flat.

For this level I used a piece of wood I had lying around, a glass vial, a plastic water bottle cap, hot glue, and a file

I first with finding the center of mass for the glass vial and marked it, then proceeded to fill it with water leaving a small bubble to act as the level. I then hot glued the water bottle cap to the glass vial to seal the water and air bubble inside. After that I placed the vial on the piece of wood and hot glued them together, and proceeded to file the wood until the air bubble was aligned with the vials center of mass.
