swallow the urge to say somethingâit is cute in a dysfunctional sort of way. I snatch up the knife and wait for John to pass over the pumpkin.
âYou think Iâm letting you anywhere near me with a sharp object?â His mouth twists into a sneer.
Galvin paces the room, inspecting our faces. âMake sure you cut all the way through,â he says, and mimes a sawing motion with his hand. âYou want the pieces to slide in and out easily.â
At the classâs combined chortling, he holds up his palm. â Mature , people. Real mature.â
I focus on Johnâs steady hand, the small tufts of dark hair on his knuckles, the way his tongue sticks out from the corner of his mouth as he concentrates on the task. The first pumpkin segment drops out, lands on the newsprint. I wipe it clean, wait, repeat.
Johnâs cheeks puff out. He cuts one tooth at a time.
âThink we could speed it up?â I say.
He looks up. His dark eyes are full of misgivings and mischief. âMaybe I like to go slow.â
âI heard you were more of a two-minute guy.â
His mouth twitches, like he canât decide whether to chuckle or sneer, as though doing either would concede a point in my favor. âStop living in the past,â he finally says, unaware of how deep those wounds cut. âYouâve been playing with boys until now. Real men live in Medina, babe.â
âYeah?â I say, raising an eyebrow. âMaybe you could point one out when you see him.â
Galvin pauses at our station, squints at the pumpkin. âOne eye is lopsided,â he says, and drops a sparkler, plus seven pea-size gray pebbles on the newsprint. They smell like the inside of fireworks, a little like rotting eggs. âThere are earplugs in the cupboard. Consider wearing them when we do the experiment.â
âSounds good to me,â John mutters.
Galvin returns to the front of the class, clears his throat. âIn 1862, Friedrich Wöhler discovered that calcium carbide and water would react to form a very flammable gas.â He scrawls a formula on the board, adds orange flames and a sad face emoticon. âWeâre going to demonstrate that reaction with our jack-oâ-lanterns.â
My skin tingles with curiosity.
âNow, slide the pumpkin segments back into placeâthe face should be intact, like you havenât carved anything,â Galvin says. âThen, turn your masterpiece around so it faces the center of the room.â
John pushes in the eyes, the nose, struggles a bit with the mouth. I shave a little flesh from the pumpkinâs mug and his teeth glide into place. âWe just needed to loosen it up a bit,â I say.
He guffaws, covers his mouth with his hand. âI guess youâd know about being loose.â
Here, I could crush him, but I bite my lower lip, refusing to take the bait. Itâs my first day, and people are already watching me, trying to figure me out. How much of me do I want to put on display? Iâve been there before, fucked up, barely recovered.
âPoke a small hole through the back of your pumpkin,â Galvin says, pausing after each instruction to ensure everyone keeps up. âAnd then pour a small layer of peroxide at the bottom of the gourd.â
As soon as I do, it begins to react with the pumpkin, starts to gurgle and froth, dissolving the skin like some kind of flesh-eating disease. John pours water into an empty tuna can, sets it in the bottom of the pumpkin, and adds the calcium carbide pebbles.
âWeâve only got a few minutes here, guys, so hereâs whatâs going to happen,â Galvin says. His voice rises, enthusiasm taking hold. The room buzzes with infectious anticipation.
âInsert your sparkler into the hole at the back of your pumpkin.â Galvin moves over to the light switch, pauses. âIâm going to turn off the lights. Count to tenâthat shouldnât be too hard,
