    Middle school science class. We were supposed to be boiling water over an alcohol burner. The kid across from me was getting frustrated because his wasn’t boiling yet. I took a look, and it just looked a little off, so I asked him if he was sure he was boiling water. He gave me a strange look and said that he thought we were boiling the alcohol. Just as he said that, his whole setup went up in flames to the ceiling and all over the table. I’m pretty sure he lost some eyebrows and needed some new pants.

      Not always, but once it starts looking different we’ve moved past asking what degree the burn is and into “do you keep the appendage that touched it?”

      If you went to the hospital in the back seat of a car? The glass looked room temperature.

          Yeah I think people can get tripped up by the fact that glass does glow red when it’s melty. Don’t fight that thought, lean into it, explain just how wildly hot glass needs to be before it looks any different and what that will do to the biology that touches it

      Yep. I’ve told many people this.

      I’ve also succumbed to confusing that schlenk connector that was just in a flame with the cold one.

      Might also be the teacher wondering why there are so many injuries and doing the experiment himself.

    Jesus! The worst I ever had was in 9th grade biology I accidentally broke a couple test tubes. I couldn’t imagine burning or cutting myself by accident or having a near death experience. 4th period would be my type of class because I wouldn’t feel comfortable at all anywhere near the other periods if they’re all getting injured.

      I sort of managed a near death experience. Not actually life threatening but it was a good show. Basically same lab, trying to boil different clear liquids out of a solution. You do it once and record the plateaus, then do it again and switch tubes at each plateau to separate them. Well we started heating it the second time and it hit the first boiling temperature, but nothing was appearing in the condensing tube. It stayed that way for a minute or so, then the temp started going up past the first boiling point with nothing having actually boiled out. I turned to ask my teacher wtf was going on, then the rubber top with the tube in it exploded off the test tube and the resulting spray of gas/mist caught fire and created a huge fireball.

      I grabbed a hot beaker stand in 8th grade. To this day I wonder if the resulting shock gave me the ability to fuck with something internally at will. When I try it feels a bit like when I had electricity running through me.

    To me this looks like early morning tiredness and afternoon tiredness, while 4th period is in the sweet spot, like maybe immediately after lunch

    When I see this meme I always remember the glass rod I stuck in my thumb when we learned to do some basic lab glassmaking.

    Early periods, kids are tired. Late periods, kids are distracted because freedom is near.

      Also, the blithe euphoria of lunch lasts less than an hour before the inescapable reality of your current situation creeps steadily back in.

      Maybe going to school at nine instead of 8 o clock would help, since most people are of owl (late) chronotype. Studies have shown, marks improve. There’s neurological and genetical proof in science. But can’t have that, since work and the world is run by the early birds.

    My theory:

    4th period everyone just wants to go home so they get er done without horsin’ around

    The other periods they have to be there anyways so lots of horsin’ round to make the time go by faster

      Don’t worry, it isn’t real. Why would they make the cuts column when there were no cuts until third period? And you can’t figure the chart just started there, and they filled out the information from second, since the second period tally marks are in different color markers.

        He could have set it up at the start of the class using information from past years.

        The “near death experience” heading being messier supports this. I imagine this was the first time that happened, so he added that in the middle of class.

    I guess some classes won’t learn how to heat stir sticks over a Bunsen burner to make glass spiral earrings and spiral rings. College Chem class allowed us to buy extra stir sticks and responsibly use our free time after labs were completed.
