Because it needs air to be present so it can dry out and harden.
When inside the tube the solvent can't evaporate, nor can the air get to the chemicals, so until they come out, they wont stick. The proper combination of stretchy and sticky polymers make good glue. ... That's why it doesn't stick to the inside of the bottle.
A glue stick is a tube of glue that can be slid onto a surface, rather than squeezed. Glue sticks are often used in elementary school classrooms.
Semi-solid adhesive in a sealed tube,
Never tried that. Stick a bottle in the freezer and see.
Possibly. Purchase a magnetic tipped extension at most auto parts stores. It is small enough to go into the tube and grab the dip stick. The above advice will probably not work if the dip stick broke along the plastic handle. I retrieved my dip stick through the use of a dowel (actually a wooden skewer) and some super glue. It took a couple of tires, but once I got the glue to set properly without touching the inside of the dip stick tube, the broken stick came right out.
Because it has no air. It needs air to make it dry enough to be sticky.
Both a lip balm and a glue stick are cylindrical in shape and come in a twist-up tube packaging. Additionally, they are both applied directly to a surface - lip balm to the lips and glue stick to paper or other materials.
Because Superglue sets up when it reacts with water. It only needs a tiny amount - the water in the air, or on human skin is quite enough. The manufacturers make sure that when the glue is put into the tube both glue and tube are bone dry. aantoon
The reason it doesn't get stuck in the tube is the same reason a box of doughnuts aren't hard as hockey pucks when you first open the package. For superglue to work it needs air to make it hard, just like the doughnut. The chemicals react with oxygen to change the chemical structure so it becomes hard and sticks to whatever it can. With the doughnut, the water is pulled out by the rest of the air in the room and it becomes hard. We're taught in high school chemistry that things go from HIGH-LOW. The more dramatic the diff and the easier it can move from HIGH - LOW, the faster the change will happen. Hope this makes sense Super glue cures in the presence of hydroxyl ions in water. No water or water vapor in the tube of super glue will keep the nozzle clog free.
The tube must be bent or pinched.
If only oxygen is in the test tube, it may burst into flame.
A puddle of glue? lol
