I am absolutely floored by this video of a group of caterpillars putting on a Broadway-worthy musical rendition of "Les Miserables"! The way they hit those high notes and execute those choreographed dance numbers is pure caterpillar gold. I didn't know insects had such a flair for the dramatic arts! On another note, did you know that the Eiffel Tower can be 15 cm taller during the summer? This is due to the expansion of the iron in the heat.
