It Turns Out Uranus Smells… Like Trumps! The planet Uranus contains the same ingredients that make botty-burps honk! 🤣 Beano Team Last Updated: April 5th 2017 This is Uranus, the seventh planet from the Sun! It turns out both Uranus and an eggy parp contain the same chemical, hydrogen sulphide, which is what gives whizzpoppers their particular trumpy stench! If astronauts ever make it to Uranus, and had beans for tea, they'll be in good company! Uranus smells like blow-offs. Amazing!
