What's Inside is a YouTube channel where Daniel (born August 1, 1984 (34 years old)) and Lincoln Markham (born January 2, 2006 (12 years old)) cut into different things to see what's inside. They had days where they were the top growing channel in all of YouTube. Amazing considering the channel started as a second-grade science project. They have done so many videos from cutting into a baseball, to even their own YouTube Gold play button. They are one of the fastest growing YouTubers.
They have worked with Studio C on the sketch "What's Inside a Bank Vault?".
