I (32M), a teacher (English and Spanish), was walking around the gym today where students were setting up their science fair projects. I stopped at a table where two of my English students (16F and 17M) had a cool-looking project. One had brought in her VR headset, and the other was acting like a scientist with a clipboard. Their project was about the nervous system, and they asked if I wanted to try their VR experience where they'd try to scare me to see my reactions. I put on the headset. It was pretty immersive, and I was trying to play it cool, but then something jumped out, and I totally lost it. I started flinching and trying to get away from whatever was in the VR. Next thing I know, I stumble and crash into a nearby table. I ripped off the headset, my glasses were crooked, and that's when I saw the damage. It was another project. These two other students were doing a chemistry project with coffee and milk, a dilution experiment with cups set out for tasting. One of them managed to jump out of the way, but his partner (14-18M) got soaked in coffee. I immediately felt like the biggest idiot. I kept apologizing. They're going to have to brew four new pots of coffee and get a new gallon of milk before the science fair starts tonight. I feel absolutely terrible that I ruined their hard work. I don't think those two are ever going to forgive me. I feel like I completely messed up the science fair, and it was entirely my fault.
