If all school lessons were taught with Oreos, I'm sure we'd all be so much smarter by now.
Australian Telescope and Binocular store Optics Central put together this neat infographic on the different phases of the moon, as portrayed by varying amounts of Oreo creme filling. For example, the perfect amount of filling? A full moon. Slightly under? The waning and waxing gibbous. Way too little filling? First and third quarters. Don't even get us started on New Moons.
Fractions, angles, circumferences — all of the Oreos for all of the school!H/T + Picthx Visual.ly
