That 'candle water level' hack from TikTok is total nonsense in my experience
I was scrolling through my feed last week and saw this video with 2 million likes claiming you can level a shelf using a candle, a glass of water, and a straw. The idea is that water finds its own level so you mark the straw position and somehow transfer that to the wall. I tried it on a 4-foot plywood shelf in my garage just to be sure, and the marks were off by nearly a half inch side to side. In my experience, a $10 bubble level from the hardware store does the job in 30 seconds with none of the mess. I get that people want a clever trick to share, but that video had zero follow up showing the actual result. Has anyone else tested this thing and found it worked for something like a picture frame maybe?
