A new, crazy social media challenge involving a vacuum cleaner and trash bags has gone viral, and health experts warn the trend could have fatal results.

It's called the Vacuum Challenge or Trash Bag Challenge.

Several YouTube videos show a person climbing into a garbage bag and letting another person suck the air out with a vacuum hose, often until it becomes so tight that the person topples over.

According to experts, the challenge can lead to cerebral hypoxia, a condition in which there is "a decrease of oxygen supply to the brain."

People who participate in the challenge alone risk getting stuck since the vacuum-sealed bags make it difficult to move.
