A boring lecture takes a turn for something less good after a student named Holly yawned vigorously during their class which cause her jaw to dislocate.
She was then rushed to a medical clinic for treatment.
Watch the video below and see what the doctor did.
With several pieces of piled Popsicle sticks, the lockjaw was treated instantly.
This simple treatment is really effective. If someone you know happened to lock his/her jaw, you can try this or not anymore. I suggest the patient should be brought to the hospital right away to avoid unnecessary incident that might happen beyond your control.
