The flame challenge is a unique competition where scientists explain scientific concepts in a way that even a child can understand. Previous competitions have explained flames, time, color, and sleep. This year’s question, though, is one that’s near and dear to my heart: “What is Sound?” The deadline for submitting an answer to the flame challenge question (either a 300 word explanation or a five-minute video) is January 19th 2016. So, for all of you scientists out there, this is your chance to share acoustics with a whole new generation of budding scientists! (Video credit Alan Alda Center for Communicating Science™)
