About This Design

Gravitational Blueshift Can Cooler

Gravitational Blueshift Can Cooler

A multi-colored, fractal representation of gravitational blueshifting; the shifting of light toward the blue end of the spectrum that occurs as photons become more energetic when falling into a gravity well. Customize by adding your own text on the reverse side. Unlike the more commonly known Doppler blueshift, an apparent effect which is the result of motion towards the observer, gravitational blueshift is real, independent of the received angle of the photon. Gravitational blueshift is a natural consequence of conservation of energy and mass-energy equivalence.

The product looks and feels great. Also giving this a 5* because of the fantastic customer support. My first order of this was not perfect and Zazzle refunded me right away so I could re-purchase. I'm not a typical review-leaver, but the customer experiance made me really happy. Crisp lines, looks great.

The printing is nice as usual for Zazzle . It's thinner than other can coolers I've had. Don't try to print anything across the center of the bottom as it's printed flat. This is my design and will likely replace this product when I fix the bottom so if your interested in the design you can find it here - zazzle.com/store/sanfordstudio.

And I have a personalized hugger with my favorite pet. I’ll be able to cherish her long after she’s gone since this hugger will last several years. Thank you Zazzle! The photos were crisp and clear, and the background color turned out exactly as selected on website.
