Sticky Notes

Legend has it that Sticky Notes were invented in the 60s by a scientist who was attempting to make a super sticky substance but made a mistake, creating the exact opposite. His error is our eternal gain, with over four quadrillion Sticky Notes now produced every single second to keep up with the public's incessant demand for something sticky but not that sticky. These tiny adhesive squares have a litany of everyday uses, from bookmarking a page in an academic paper through to leaving passive-aggressive notes telling your roommate to stop ejaculating in the shower.
