About This Design
Gravitational Blueshift Favour Box
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.

We could have had a bigger font but otherwise, the colours are great. It is sligthly smaller than I thought, but it's fine.

Paper Favour Box, Popcorn 9.525 cm x 8.89 cm x 19.05 cm
Hi Ladies, these popcorn boxes were the right size and favor for my event. The boxes hold 2-1/2 cups of popcorn. Please use a plastic insert when filling with popcorn. The boxes are not food grade. I put tissue paper in the bottom of the boxes when displaying for cosmetic reasons only. You will love these boxes. .
