American teens have started a new dangerous fad called the "Eraser Challenge", which involves taking an eraser and rubbing it back and forth across their arm while reciting the alphabet and coming up with a word for each letter.
The students show their red skins to their friends, once they reach the letter Z, while the students who broke the skin while playing the game passed of their body fluids to others with the eraser, Fox News reported.
Bethel Middle School has sent a warning letter to the parents about the "troubling" activity that teens across the country have been getting involved in, while asking them to talk to their children about it.
