Скачать или смотреть How Were Sticky Notes Invented? 🤯

Unlock the surprising truth behind the accidental invention of sticky notes and the ingenious science of their unique 'weak' glue, featuring revolutionary microspheres. This #YouTubeShorts explores how a 3M scientist, aiming for a super-strong adhesive in 1968, instead stumbled upon a low-tack formula that was initially deemed a failure and shelved. Years later, a clever colleague's problem with slipping bookmarks brought this forgotten glue back into the spotlight, leading to the creation of the iconic Post-it Note. Discover the microscopic world of bouncy 'microspheres' – the secret ingredient within the adhesive that allows sticky notes to make only partial contact with surfaces. This enables them to stick gently, peel off cleanly without residue, and crucially, regain shape to be reused again and again! It's an amazing tale of innovation where a scientific 'mistake' transformed into the essential Post-it Note. Did you know they were first yellow because it was the only scrap paper available? What's YOUR favorite accidental invention?
