The "Mio" thread bump
In my youth I was quite the trouble maker...around grade 7 some (40+ years ago) I discovered if I cut off my sneaker lace tip and shoved one of Mom's straight pins thru the back of the plastic tip (cut the lace tip around 1/4" before plastic end) so the pin goes thru the frayed lace end.....You can make one hell of an accurate Blow Dart (grab extra milk straws during lunch period). The darts stick amazingly well to the back of the teacher in whatever class you have following lunch!
Warning: Make sure NOT to hit said Teacher's exposed skin ESPECIALLY the back of the neck unless you enjoy the Dean's office and subsequent phone call to the parents!
I doubt highly that anyone in grades 5 thru 12 will be reading this but, either way the above was a theoretic version of what the darts could be used for. I myself would never actually aim them towards any person or animal. 😉
Apparently I was not alone in this discovery? Others must have been punished by their mother and sent to their room and not allowed to come out for hours on end....
