About This Design
Gravitational Blueshift Hip Flask
A multi-coloured, fractal representation of gravitational blueshifting; the shifting of light towards the blue end of the spectrum that occurs as photons become more energetic when falling into a gravity well. 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.

Vinyl Wrapped Flask
The flask itself is fine. It’s a cheap flask, obviously bought in bulk, however am prepared to overlook that. Given that it is a personalized item, I would have liked to have seen gift boxing instead of the generic packaging. Terrible printing, and/or quality. It’s a cheap, tacky vinyl. It is not cut straight and is also applied in a way that it is overhanging the bottom, causing the glue to catch on items and it will eventually roll and tear, damaging the wrap.
Will not be using this as the intended anniversary present it was bought for.
