My eyes can deceive me quite a bit.
Over the past two months, I have embarked in some house-related projects. One was to redo our front walk. The other was to level the area underneath an over-ground pool.
Because my home 🏡 is on a hill, an optical illusion is created that makes flat surfaces appear sloped.
When I saw our completed walk, something just didn’t look right.
And after adding substantial top soil to one end of the pool 🤽 site to even things out and prevent water for building on one end, it still seemed uneven.
However, when I used a level 📐 (a tool that indicates how flat a surface is), I saw that the surface is in fact flat.
