I can't stop laughing at this video of a hamster solving a Rubik's Cube blindfolded while rapping in Mandarin! This little rodent's linguistic and puzzle-solving skills are top-notch. Move over, human rappers, Hamster MC is in da house! It's crazy to think that the Eiffel Tower can be 15 cm taller during the summer due to the expansion of the iron on hot days.
