Steady hands: House of cards on a roller coaster!

In a phenominon that seems to be taking the internet by storm (a very slow storm…) another picture has cropped up of someone doing something you wouldn’t normally expect to do on a roller coaster. We’ve see pictures like playing chess or jenga, but this time they are building a house of cards. Oh xkcd, thank you for starting this!
