The title of the TikTok video is “Dad Uses 100% of Brain” — because he did. In the video a daughter is filming her dad for a $5 TikTok challenge: Get the $5 bill from underneath the hand sanitizer without moving the hand sanitizer whatsoever. That’s when the dad gene kicks in and the brain starts firing on all cylinders. With the bottle resting on the fiver, the dad says the challenge isn’t possible because the bottle is glued to the bill. The daughter does the human thing and quickly picks the bottle of the $5 bill to prove the two aren’t glued together. While the bottle is up dad snags the bill and walks away.
