For years, Dan and his son Lincoln have been cutting the world’s items open to see what’s inside, and their YouTube channel What’s Inside? has finally gotten around to the question we’ve all been asking: What is really inside an authentic Marshmello helmet?

Apart from getting treated to backstage offerings like Captain Crunch donuts, Marshmello gave the YouTube duo one of his own authentic helmets, complete with dual signatures on top. Unfortunately, they couldn’t get the newer LED version, since airport TSA broke one of the helmets and there isn’t a spare for What’s Inside? to explore.

Watch the video below to hear Marshmello’s plans for future helmets, how much each one costs, how they’re made, and of course, what’s inside.
