The milk crate challenge, also known as the crate challenge, is a video challenge that became viral online in August 2021. The challenge involves stacking milk crates into a structure that resembles a podium, with both sides of the structure functioning as stairs. The participant is expected to climb up to the top of the crates and climb back down without destroying the structure or falling, risking injury. The activity has faced criticism by health professionals for its unnecessary risk to personal health. Social media platform TikTok that helped popularize the trend said it would eliminate search results for "milk crate challenge" citing its policy that "prohibits content that promotes or glorifies dangerous acts." Some on social media described the challenge as an event in the "Hood Olympics".
