A Pop-It (also known as Go Pop and LastOne Lost)[1] is a fidget toy consisting of a usually-brightly colored silicone tray with poppable bubbles, similar to bubble wrap, that can be flipped and re-used. They come in a variety of colors, shapes, and sizes, and even come in wearable formats. It is marketed as a stress-reliever and rose in popularity in the spring of 2021 due to TikTok influencers as well as boredom and stress attributed to the COVID-19 pandemic.[2][3][4][5][6]
