During an interview with James Corden, Stranger Things star Millie Bobby Brown revealed how she gets her character's nose to bleed on demand. It's a clever trick that involves corn syrup.
It's a good idea to spit out any blood that collects in your throat and mouth, since it can irritate your stomach and cause vomiting.
Nose bleeds are caused by pressure inside your skull, which is made up of your brain and blood vessels. If you swallow blood, it can irritate your stomach and make the bleeding worse.
If you're a teenager, don't be afraid to have your nose bleed; it's natural and it can be helpful if you have migraines.
During the first season of Stranger Things, we learned that the telekinetic girl had a very rough past. She was once shaved by evil scientist Dr. Brenner (Matthew Modine) in order to conduct experiments on her telekinesis.
But now, the buzz cut is back, and it's an achievement that Brown herself is pretty proud of. Fortunately, she and her hairstylist Sarah Hindsgaul worked hard to hide that buzz cut in the show.
It was difficult to get the shaved look on Brown, especially because it needed to match her own long hair. But it was worth it for the dramatic effect.
We'll see if that buzz cut will stick around in the future. If it does, it's likely to be a very important part of Eleven's storyline.
