  • Constellations emerge before your very eyes on this star covered mug when a hot beverage of your choice is poured inside. These color-changing mugs are thermochromatic, which is a scientific word for magic. The crystals in the black thermochromatic ink change conformation (shape or structure) when exposed to heat (such as a hot beverage) to reveal the constellations underneath. Nothing goes better with coffee than science!

    Constellations included: Cassiopeia, Perseus, Sagittarius, Hercules, Andromeda, Scorpius, Taurus, Ursa Major (Big Dipper), Ursa Minor (Little Dipper), Orion, Castor & Pollux.
