• Ever had trouble trying to squeeze out those pesky last drops of ketchup from a bottle?
  • TikToker Casey Rieger has a life hack for you.
  • It involves swinging the bottle with your arm in a circular motion like a rock star.

What happens when you combine the effects of centrifugal force, the last bits of a ketchup bottle, and TikTok? A viral video, of course.

That's what a content creator named Casey Rieger discovered after uploading a video to TikTok on August 30.

"Okay, I saw somebody do this on TikTok and thought it was genius. So I'm gonna give it a try," Rieger said in the video as she held up a bottle of Heinz ketchup. Rieger started her TikTok account in 2020 and has over 276,000 followers.

"You know when you want that last bit of ketchup and then you just. Most people hit it on their palm like that," Rieger said, demonstrating the motion with a mostly empty bottle of Heinz ketchup in her hand. 

"But if you want to get the whole bottle?" Rieger asked.

Rieger then swung her arm — and the bottle — around in a big, circular motion several times before showing off the results for the camera: The ketchup had become concentrated near the bottle cap.

"How cool is that?" Rieger said at the end of the video.

Rieger's video has been viewed over 15 million times and received over 20,000 comments as of press time. The comments are full of people joking that they've injured themselves doing the same trick, reminding people to hold the cap shut while they swing the bottle, and a couple of people correctly identifying the hack as centrifugal force at work.

Some people told complimented Rieger's form in the video.

"You Elvised it," said one person on TikTok.

"Cool, also you look like at a rock concert playing guitar," another person commented.

At least one other person wrote that there's a simpler way to empty the bottle. 

"Store it upside down dudd," read one TikTok comment.

Representatives for Heinz and Rieger did not immediately respond to a request for comment from Insider sent outside regular business hours.
