Let me add to that list: Fun short animations on physics topics: https://www.youtube.com/c/minutephysics Chemistry that I didn't realize could be done at home: https://www.youtube.com/c/Nighthawkinlight Similar to Veritasium and SmarterEveryDay: https://www.youtube.com/c/SteveMould Advanced physics explained very very well: https://www.youtube.com/c/Scienceasylum Build things you'd think you could only find on amazon: https://www.youtube.com/c/DIYPerks Dude making lenses and doing shit with glass that I didn't think was possible: https://www.youtube.com/c/HuygensOptics Engineering perspective on making useful shit at home: https://www.youtube.com/c/TechIngredients Home/Lab science experiments including metal coating, DNA tampering, or even receiving & decoding weather images direct from satellites flying overhead: https://www.youtube.com/c/thethoughtemporium Civic Engineering topics: https://www.youtube.com/c/PracticalEngineeringChannel EDIT...almost forgot this guy who must be well funded and does other insane experiments in his home lab: fun with x-rays and plasma, make holograms, make LCD screens, reverse engineer shit, manufacturing tips, etc.: https://www.youtube.com/c/AppliedScience
