Praising Unglamorous American ingenuity
Crying is not usually in my mind, which is why my partner Richard presented me with a beautiful cutting board he made - a hard Eastern maple, burnt through with purple veins of African padauk - thought I trees I just have to grow in very complex ways that I never noticed. It was only when I heard him and his wooden colleagues talking about "glue" that I realized that a wild catcher was involved in mixing woods, and the wonders of this material are greatly reduced when we say it with the best name used for Elmer.
Wood glue - again without much ridicule - has turned outside the ground. There are names associated with radicalism in adhesives: Mildred Bonney and Langdon T. Williams, the couple who founded the adhesive company Franklin International in 1935 in Columbus, Ohio, who released their famous product, Titebond, in in 1955. Titebond is a polyvinyl acetate (PVA) glue. He presses the threads of pieces of wood, so they interweave; as the glue dries, the threads shrink to their normal size, but are now so trapped that the bond is virtually unbroken.
While some luthiers still use animal glue when lifting stringed instruments - yes, the kind that was donated from animal hides - most woodworkers have switched to PVA, and especially Titebond, and especially (for projects that require it) Titebond III, which gives arias confidence. all over the internet woodworking, as it considers itself full of water, although they admit that some pundits have doubts. There is also an "open time", which means it stays glued and does not dry out even if you disregard how to prepare your wood for a full 10 minutes. Titebond II will give you just five.
But the real break with all the Titebonds is, of course, the connection. What level of cracking, tightening, flexion, flexion, impact, tension or peeling is required to break the Titebond link plane? This is measured in pounds per square inch, and Titebond III will take up to 4,000 lbs for a break. Two freaking tons. Hardwood will break before this call.
From glue to eyes. And while old - fashioned false eyes need to be glued, it's much weaker than Titebond - and that's enough to think about hard - eyed eyelids. What is new in eyelashes is a synthetic prostaglandin analog called bimatoprost. (A synthetic prostaglandin analog is also an active ingredient in misoprostol, one of the approved pills for self-guided generation.) Where chemical engineers can find out how ultrasonic devices and PVA glue work, bimatoprost is a a tragic accident, and something of a mystery. Basically, ophthalmologic researchers worked to reduce pressure in the eyes of glaucoma patients, and found that bimatoprost relaxes the ciliary - the anxious muscle in the eye that causes damage when which we read on our smartphones - which caused an outflow of water inside an eye. They were surprised to discover that this movement of plasma-like flow was also the Miracle-Gro for eyes.
Given that the ingenuity of technology that makes human hair seem to be the ultimate desire of man, this was a delight. “Hypotrichosis,” or what the National Institutes of Health calls a “sufficient amount of ointment,” are the bimatoprost disorder treatments, seen in people with alopecia, but in fact the fertilizer has more subtle applications. Interestingly, bimatoprost may even induce hypertrichosis - excessive growth in eyesight, generating a luscious, abundant fringe over the eye that avoids the need for thick mascara paint. “These hair looked stronger,” the NIH study found, “they were longer, thicker and more colorful, and rose at a sharper angle from the skin than they were in the hair. control eye. ”The only take? Hypertrichosis caused by bimatoprost sometimes comes with “irregular pattern of lash curls. ”OH HELL NO.
