gizmodo.com Sabina Graves 2025-09-18 05:45:58

Popcorn buckets are becoming must-have toy collectibles, and this plot twist of trends comes from the unhinged virality of containers that evoke pop culture icons and hold tasty snacks. As a theme park nerd, I saw it unfold as Disney Parks’ snack of choice went from the general cylindrical plastic bucket to Mickey Mouse-shaped holiday containers. As is common in the age of social media, the buckets became coveted souvenirs—and like many sought-after collectibles, scalpers soon got into the game

The Meta AI app is a privacy disaster

When you ask the AI a question, you have the option of hitting a share button, which then directs you to a screen showing a preview of the post, which you can then publish. But some users appear bl
