Speaking of styropyro, he's very adept at sourcing less than savory laser parts and has no qualms putting those extremely high wattages to crazy uses. I'm still not sure the guy isn't blind and just faking it really well. No, really. I've got spots in my vision from using >5W lasers, I've no idea how he doesn't (Pro-Tip: don't put wedding rings in the laser path)

Nile Red is also really good at chemistry and seems to have no qualms doing questionable stuff. Think 'Things I Won't Work With', and then he works with it, a lot. Thank God he's not too into amines ... yet. The algorithm is going to push him ever more towards the boom-boom side of chemistry and he can only resist so long.

Speaking in prosecutor-terms, these guys more than have the means and opportunity, they need only the motive and the case is a slam dunk. The lines they walk are quite fine.

All that said, I love these guys and have for years. I'll continue to watch and support them as long as they can continue to upload, which is never a sure thing in their cases
