In the video, a man with long hair and a beard is standing in front of a blackboard. He is holding a red marker in his right hand and a green marker in his left hand. The blackboard has the words \"Because Science\" written at the top in pink letters, followed by a series of numbers and lines. The man is speaking and appears to be explaining something related to the content on the blackboard. He points to the blackboard with his markers as he speaks.
