Perhaps safer than overdoing it on the Adderall, some hardcore Chinese students cramming for exams have devised a hair-raising contraption that prevents them from falling asleep while studying.

Photos like the ones posted here, are showing up on the Chinese website, Wiebo. 

Honestly, I could totally use a contraption like this while standing in line at the DMV.
