The B 52's - Private Idaho

Bob Kramer Makes a Damascus Blade out of Steel Cable

AeroMechanical says...

I believe he is wearing eye protection. Regular looking glasses with polycarbonate lenses are cool with OSHA for most (non splashy chemical) things. You should have the little side protection blinder thingies (can't tell if he does), but I don't believe it's necessary.

Man invents machine to turn Plastic into Oil

MarineGunrock says...

As someone with experience in the manufacture of various plastics:

AHEM. By looking on the bottom of different plastic containers, you'll notice the "recyclable" symbol made of three curved arrows forming a triangle, as well as a polymer code, such as PE, PC, HDPE, PP, PS, V, LDPE or PETE. These indicate the type of plastic used in the product. PE would be polyethylene, HDPE is High Density polyethylene, PC would be polycarbonate, PP for Polypropylene, Polystyrene, Vinyl/Poly vinyl chloride (PVC) and polyethylene terephthalate.

The polyethelylenes and PP melt at lower temperatures (300-400 F)
PS melts higher at around 450 for a good liquid form and
PC melts the highest at 560-650 or higher.

So yeah, you're sucking a lot of juice to melt these - a lot more than you can pull from a few photovoltaics, anyway.

CD Bubble Blowing

Asmo says...

>> ^kulpims:
i think that's the blank, polycarbonate disc that you get with every pack... I don't see how you could do this with a normal cd with the aluminum layer
edit: or maybe it's magic


Tried it, didn't work, just end up with a burn't hole in the PCarb. The material is quite dense (you can't poke through it when melty with a metal object)

Guessing it's one of the thin laminate layers, it would have to be super thin to heat so fast.

FDA Failing You: Govt Says BPA IS Good For You

MarineGunrock says...

1) "Not dangerous" != "good for you"
2) BPA is only dangerous in high levels.
3) Regular water bottles do NOT contain BPA - only hard ones like Nalgene bottles. They are made with PC or Polycarbonate. BPA is an additive to PC because of it's strength.


I won't downvote it because you're a probie, but I'm not gonna upvote it.

Impossible Promo Approval Guy

MarineGunrock says...

I'm sorry, but none of this is funny unless you actually know what the fuck they're talking about. Obviously these are inner-industry jokes.

I really hope this doesn't make it for that fact and also because it's not even a video.


I mean, how funny would it be to all of the sift if I made one of these talking about "Mr. Insistent on ordering polycarbonate guy"?
