Caffeine + Brain Heat Change Mega Mug
When the mug is cold, you'll see how your brain looks before the infusion of caffeine. As you fill it up and the mug warms, the design changes to show your wide-awake, post-caffeine brain.

Great gift, fast shipping. My boyfriend really loved it! Very cool heat changing effect.
These small notebooks will make a great stocking stuffer- they're not flimsy even for their size and should hold up pretty well! The art on each one is very detailed and they look great.
I ordered this mug as a Christmas present for my boyfriend who's currently in his first year of a neuroscience phD program, and I already know he's going to love it! It loks exactly as picture, is MASSIVE, and seems very sturdy. It originally shipped quickly, but the handle was broken during transit. I contacted Cognitive Surplus about this and their customer service was wonderful. They shipped me a brand new mug, which arrived even faster than the first, and is in perfect condition. I highly reccomend this mug and this company! Will be hopefully ordering again in the future.
I bought this for myself. I got it because of the amazing design and that it has a unique feature: that it changes its appearance when hot water is added. It my favorite mug! I’m so happy with it.
