Input: Text: i have a classmate who is really interested in guns, knives, explosives etc., we'll call him a.

many weeks back, i took back some magnesium powder from the school lab for campfire effects. a saw me placing it inside my locker, and offered to trade a spoonful of magnesium for a handmade firecracker explosive. i agreed, as it sounded pretty awesome. it looked like a cherry bomb but it was really small. he told me that all i had to do was to light up the fuse and wait for it to explode.

today i attempted to detonate it in class. that was the first mistake because its an enclosed classroom. everyone else was at other lessons so it was empty. moving the tables to the side, i created a space where it could "safely detonate". lighting it, i ran to the back of class and took cover. the fuse was a sparkler and it burnt all the way till the flash powder, but nothing happened. i took out the fuse and realized that the portion of it inside the flash powder had already disintegrated.

this is the stupid part.

i didn't know what i was thinking. maybe i thought it was a dud or something. i took my lighter and lit the rest of it. my left hand (thumb, index and middle finger) was holding it when it exploded. it was really loud and made me go partially deaf for the next 5 minutes. my fingertips are heavily bruised and there is a bit of internal bleeding under my middle fingernail. 

right now i'm suffering from tinnitus in my left ear as i type with only my right hand. my left hand is in a sock with ointment on it. my only fear of this is that my hearing may be damaged and this could result in me not being able to go for a private pilot license course i plan to take up at the end of the year. if anyone has shot guns without earplugs before, you may know what i'm going through now. do advise.

i didn't dare to tell my parents the truth, so i told them i smashed my fingers in the doorway. for the hearing issue, i'm not sure how i'm gonna explain that.

p.s i think this is karma, because i drew a huge realistic penis on my friend's physics workbook yesterday. doesn't help that the 3 fingers injured form fleming's left hand rule.


 

update: fingers and hearing pretty much back to normal, now i've paid the price of stupidity. now i think through everything many times before making a decision to avoid future fus. have a nice day.
