I was homeschooled previously with a small group of other children and we fart in class all the time.
Now I'm in public school for high school and no one is farting. I was very sheltered and public school is like a whole new world for me, so I don't know what the norms are. I've been holding it in but my stomach hurts and it leaks out anyway.
I don't understand how there are so many more people in high school and yet zero farts...
The key is to unevenly shift your weight (lift one side and slowly allow it out), if you are level with the seat it usually creates an airlock or whatever which will amplify the force and volume created the moment theres a pressure leak/change.
Also, before you go, lie down on your stomach and try to get yourself so your lower half is elevated the highest and relax while the gas floats to the top 😁 Better out than in before school because then your day will be ruined from stomach pain
There were many days I had to find an empty classroom or office to plank in to clear the air, err, my stomach
