THey usually come with a tight cap -Use it. If you've lost it, then plug the end with a dowel or similar.
Try warming the tube with a hairdryer or soaking it in warm water to soften the adhesive. Then, use a toothpick or cotton swab to gently push the adhesive out of the tube. Additionally, you can try using a blunt object like the back of a spoon to push the adhesive out.
Liquid rises in a capillary tube due to capillary action, which is the result of adhesive and cohesive forces between the liquid and the tube. Adhesive forces between the liquid and the tube's surface cause the liquid to be attracted to the tube, while cohesive forces within the liquid molecules help pull the liquid up the tube against gravity.

Chest tube clogging can lead to infection. The chest tube is there to remove fluid from around the lung. If the tube becomes clogged, the fluid builds up around the lung. This fluid can become infected, which is called an empyema. An empyema can require a major operation to remove the thick and infected material from around the lung. Chest tube are more frequently being left in for home care and the patient discharged from home. If the tube stops draining, it either means there is no more fluid to drain, or the tube is clogged. If the tube is clogged and the fluid accumulates, this is a set up for an infection related to a clogged tube.
This happens due to the difference in adhesive and cohesive forces. Water molecules are more attracted to the walls of the tube (adhesive forces) than to each other (cohesive forces), causing water to rise. Mercury has stronger cohesive forces compared to adhesive forces, so mercury is more attracted to itself than to the walls of the tube, causing it to be depressed or fall in the capillary tube.
It is a speedometer pick up tube.no longer used due to clogging.
I would not use superglue in an Aquarium. I think there may be something on the superglue containers/tube stating that it is not for use in water.
Mercury falls in a capillary tube due to the combination of capillary action and gravity. Capillary action is the tendency of a liquid to be drawn up into a narrow tube against the force of gravity. When the adhesive forces between the mercury and the walls of the capillary tube are greater than the cohesive forces within the mercury, the mercury will move downward in the tube.
A bicycle tube patch kit typically includes patches, sandpaper, and adhesive. These items are used to repair punctures or holes in a bicycle inner tube.
It is because of Capillary action, the adhesive forces for water are effective in narrow tube, in a wide tube the weight of water resists the upwards movement of water.

To repair a punctured bike tube, the best way is to first locate the puncture, then use a patch kit to seal the hole. Inflate the tube slightly to help find the puncture, clean and roughen the area around it, apply the patch and adhesive, and press firmly to ensure a secure seal. Finally, wait for the adhesive to dry before reinserting the tube into the tire and reinflating it.
