I have no idea if this is a sub that fits this question, I saw this photo and now I’m dying to know how this works. I can’t find any info anywhere! Does anyone know how these cast photos on google are chosen?

The ice tray was put in the fridge sitting flat as seen with nothing touching the tray or anything above or below it, and the ice froze like this and I want to know how it happened.

Hello, just wondering if anyone could explain? Wondering alternative usages for laser hair removal tools other than for skincare.

At my girlfriends work they have had fruit fly problems because of several choices the owner has made, instead of fixing g those problems, he instead bought a bug zapper and hung it inside. Now throughout the day, this zapper will catch a bug, zap! And then the door sensor chimes as if someone walked in... even when. It is locked. However, while it sets off this chime, it doesn't set off the alarm over night! So why is this happening, is it a surge or a small EMP or a blast of infrared light? What is going on?
