Battery Morph Heat Changing Mug

Me before caffeine vs me after caffeine... Watch your battery charge right in front of your eyes as your pour your hot coffee or tea into the magic morphing mug! 

Made of thermographic inks, these mugs react to heat, revealing a new and fun artwork. As your beverage cools, the graphics change back to their original state.
