Glue used to be rare and magical.

Before or after going to school uphill?
- Which direction too? It's uphill both ways
- back in my day we used wax or pine sap to stick things together and we liked it. We LOVED it!

Of all the technological change I've lived to see, glue and tape have improved the most.
- Over the past 200 years, chemistry has taken massive leaps forward. A lot of guesswork and mystery is now gone, but that doesn’t mean there are no perplexing problems to solve. Most of the simple cases are pretty clear, and you can predict the result with a few simple formulas. When you start talking about more complex cases, there’s still much to be done.
- There's this tape called frog tape. It's quite amazing. Uses powerful science
  And gorilla tape can remove your skin
  And silicone tape fuses to itself molecularly
- I guess Tesla missed that memo then..
  
  Doesn't matter how good thing have gotten when you choose to be cheap and use the wrong stuff.
  Same thing with their leaking displays because they ignored the extreme heat minimums real car manufacturers used.
- It's actually funny going back and watching early episodes of The New Yankee Workshop and hearing Norm brag about the "new" glues that were coming available. "This is a one-part glue, you don't have to mix it up, it's ready to use in the bottle, it's water proof and it cleans up with water! I wouldn't have even tried doing this myself without these modern glues." They avoided showing brand names and such on the show; Norm was usually careful to hold the glue bottle with the back facing the camera, but he's clearly holding a bottle of Titebond 2, with it's blue cap.
  And I mean, yeah. imagine building furniture without PVA glue, you change how you think.

Pine pitch is actually pretty strong stuff, but nowhere near as convenient as picking up a tube of glue from a store.

Egg is pretty good.

I'm pretty sure we had glue before we were even our current species.
- It’s the glue definition of reversed Theseus.
  We started with a sticky mess. Now we have strong adhesive. The technology evolved from the one to the other but are they still the same thing?
- Like what? Spit? Poop? Semen?
  
  Like gelatin, casein, starch, horn glues? They are old as dirt.
  
  Tree resin you can get ahold of on accident, light a green piece of wood on fire, you get glue. Animal products can turn to glue with again just leaving it in a fire a long time or a hot enough fire. Humans have been making stone and other tools a lot longer than Homo Sapiens have been around.
  
  Where do you think Gorilla Glue comes from?

wax or pine sap
How the hell do you huff those though?
- With the ghost of solvents past.

Why did I read this and my inner voice had a whistling tooth on the S’s?

Me playing hidden object games seeing a tree with sap coming out of it 👀👀👀
