This link will bring you to a Tumblr post. This post contains a soundtrack called "The masters drumbeat". It repeats itself over and over again and is supposed to be annoying/disturbing and can apparently give you a headache (in some cases, it didn't for me)

The challenge is to last as long as possible, and to add to the challenge, I want you to do this using headphones ;) 

I'd also like you to tell me how long you lasted! 

 

I made it through the whole thing..

 

Good luck! 

Cheers! //Fridolf.K
