Four years after the Ice Bucket Challenge raised $115 million for the fight against ALS,sex video hd there's a new challenge springing up to raise awareness for an aggressive type of brain tumor that affects young children.

The Lemon Face Challenge is raising funds to combat diffuse intrinsic pontine gliomas (DIPG), an oft-terminal form of cancer in the brainstem that most commonly effects children aged 5 to 9 years old.

Instead of dumping ice-cold water on themselves, participants in the challenge are eating entire wedges of lemon and posting their best sour faces online. The challenge is meant to raise awareness of DIPG and encourage people to donate to the fight against it (h/t Washington Post).

The Lemon Face Challenge was started by 11-year-old Aubreigh Nicholas, who was diagnosed with DIPG in September. Her charity, Aubreigh's Army, has already raised more than $40,000 at the time of this writing thanks to some help from the sports world.

Legendary Alabama football coach Nick Saban kicked off the challenge in support of Aubreigh and the fight against DIPG.

Saban inspired the Los Angeles Dodgers to follow suit with the team eating a bunch of lemons and challenging their rivals, the Arizona Diamondbacks, to try it as well.

Hopefully the Lemon Face Challenge will pick up steam across the world as more and more people get involved and the word gets out. The hashtag has already picked up quite a response.

With all of the money that people raised for ALS research in 2014, a study was funded that discovered a new gene associated with ALS — a potential good option for gene therapy for people with ALS.
