Vine artist Brandon Bowen has publicised his invention for a device that blocks out haters. The paper investigates the extent to which this ‘hater blocker’ can block haters by looking at the estimated light absorbance of the material. It is conjectured that the spoons, that the device is made up of, is polyethylene with an absorption coefficient of 103.85 cm-1 and an average thickness of 1.12 mm. It is calculated that the hater blocking device would be able to block 99.99% of haters but it has design faults which may hinder this value. Limitations in the amount of information known about the spoon’s material properties impact the reliability and accuracy of the determined value
