Breaking Taps

I’ve been following the YouTube channel Breaking Taps for quite a long time. It’s a fun mix of science, engineering and technology covering physics and the occasional bit of chemistry with some just flat out cool experiments, crazy tech and fascinating slow motion in between – like that time when he made his own scanning laser microscope (it’s pretty cool, you should watch it).

Well, now he’s having a go at making some optical lens elements. And it turns out, making lenses from epoxy resin is a bit more difficult than one might initially think.
