If someone tries to steal or fight me, I guess I'll just vomit on them :)

So glad I'm not eating anything while watching this.

I didn't know I wanted to learn about defensive vomiting until today! Great video! :)

I think the reusing of the shoe on your wall is an excellent reuse of recycled materials. Kudos.

My son had the flu a couple days ago and looked just like one of those puking baby birds, I showed him the video and he flipped me off!🤣🤣🤣🤣

1:46 I can't stop imagining that's a video game enemy attacking me.

"A hungry predator might lose its appetite if its lunch suddenly came with a side of barf."

The most repulsive part of this video to me was the criminal failure to say, "A hungry predator might lose its appetite if its lunch were to suddenly lose its lunch."

This is the first video I've seen of Gross Science. It was entertaining and informative. Thank you and well done Ms. Science!

[BensLab]

turning sickness into a video. genius.

[SunnyApples]

Gross, so both bugs and birds that eat them puke as a defense.
Would you call that convergent evolution?

[TheWASHINGMACHINEBOY]

i have an angry birds book that tells you how real birds defend their eggs and the bird that vomits bile is one of those birds

[shadesevendust]

Other animals: *growls and snaps to scare away predators*
Birds: back off cuz before I puke on you

[jamesnguyen]

Well that explains that burning sensation and the weird orange brownish spots i got as a kid while collecting grasshopper

[giuseppebadala]

If a birt vomits on me i'm probably gonna vomit on him for the disgust
