Some people build fences or plant flowers in their backyards. Others build contraptions that raise more questions than answers. Whether it’s a trash can full of sweet tea, a DIY pool wrapped in caution tape, or footballs used as makeshift suspension, these wildly creative solutions show what happens when duct tape, overconfidence, and boredom collide. Here are 20 examples of backyard engineering that technically work but probably shouldn’t.
