Since then, thousands of accounts have filmed the trick themselves to see if it works, including easyJet.
Cabin crew were filmed showing customers how to do it on their upcoming flights, in a video posted to the airline's TikTok account on August 24.
The video also reminds customers to leave the sick bags behind after they use them, so other passengers can use the bags and reduce waste.
EasyJet responded to the crazy by getting the cabin crew to film a demonstration for all their customers to try it on their upcoming flights.
"Game changer? We think so," they wrote in the caption.
The clip, posted to the airline's social media accounts on August 24, also takes a moment to remind customers to leave the sickbags behind for the next passenger to use and help reduce waste.
EasyJet's Cabin Services Director Tina Milton said the video was an example of how the airline goes above and beyond for customers.
"Our crew go the extra mile to make sure our passengers have enjoyable flight and so they have been inspired to create our very own inflight demonstration video to show how to recreate this creative hack," she said.
