Every neighborhood seems to have at least one person who looks at a dangerous problem and thinks, “I’ve got an idea.” Sometimes those homemade solutions are surprisingly clever. Other times they leave everyone else wondering how nobody ended up in the emergency room. There is a fine line between creativity and complete chaos, and these projects charge right past it.

The photos in this collection celebrate the kind of DIY engineering that probably should have stayed on the drawing board. Whether it is an improvised repair or a shortcut that ignored every basic safety rule, each one is equal parts impressive and alarming. You have to admire the confidence, even if you would never want to test any of them yourself. Let’s take a look at 20 examples of backyard engineering that are way too risky.

1. “Footballs to increase the payload on my economy car.”
