Resin, sometimes called “essential oil,” is a gooey, almost adhesive substance that produces all of the medical and euphoric molecules of cannabis. Our cells obviously have to stick to each other and to the non-cell parts of the body (bones and all the other stuff ) or we’d simply fall apart. It’s this resin (or essential oil) that gives sticky weed its name. Some of the hydrogen atoms will stick to the closest surface, some will grab onto the hydrogen molecules in the liquid, and some will bond with another hydrogen or oxygen atom in the sugar. The part of a bag of pot that’s actually sticky is the resin (not to be confused with rosin). Gizmo, you will discover what causes this “stickiness.” You will investigate a variety of phenomena that result from the attraction of molecules to one another. The lone pairs on the oxygen molecule create a "bent" shape (the valence electron pairs repel the O-H bonds, folding them together at an angle of ~104.5). The strong Coulomb attraction between the molecules draws them together or makes them "sticky." Now just as the environment can cause rubber to crack, flake and decay — “dry rot” — it can also cause the rubber to revert back to its original state. Sticky Molecules. When the water evaporates, only the sticky polymers remain in the glue. the polarity of the O-H bonds and the asymmetry of the molecule. Or like maple syrup for those of you who’ve already had enough biology for the day. The amount of each starch, which is different for every type of rice, determines the texture of the cooked rice and whether it will be fluffy, creamy or sticky. The result: a sticky mess. As rice cooks, both the heat and liquid penetrate the grain and the starch molecules inside the grain break down. Because the water molecules are more strongly attracted to each other than to other molecules, they form droplets on surfaces (e.g., dew drops) and form a dome when filling a container before spilling over the sides. A sticky subject Staying in one piece is very important for any organism that consists of more than one cell (that’s everything except bacteria and things like amoebas). W. ater. That causes the water in the glue to evaporate, or change from a liquid to a gas. Vulcanization causes the polymer chains of the latex to join together into a network that increases the molecular weight and causes the material to be stretchy — and no longer sticky. Polarity) to the simulation area. Sticky product means size of polymeric molecules is comparatively low and to get solid you have to ensure by controlling the polymerization conditions such that you get long chain polymeric molecules. Drag the dropper over the dish to add water. and a Petri dish (labeled . As the liquid is absorbed, each starch carries out a different task. the O-H bond has a dipole moment of ~1.4, a strongly polar bond creating partial charges (neg on oxygen, positive on hydrogen). Sticky weed (or “sticky icky”) is a slang term for marijuana flowers that still contain a good deal of resin in their trichomes. This misfolding causes the proteins to get sticky, and that can promote clumping, or aggregation, which is the hallmark of several neurodegenerative diseases … If you hold sugar in your hand, even a tiny amount of sweat can make things start to get sticky.
