Maybe a tube made of glass?
Is there something more to this question I don't get?
You can shorten the length of a glass tube by using a glass cutter to score a line around the tube where you want it to be cut. Then, apply pressure on both sides of the score line to snap the tube at the desired length. Be sure to wear appropriate safety gear, such as gloves and goggles, while cutting glass.
The glass tube in a fire sprinkler expands less than the liquid inside the tube when exposed to heat. This difference in expansion causes the glass tube to break and activate the sprinkler system in the event of a fire.
You smoke the bath salt "from" the glass tube not on it
The tube that contains only glass beads is called the control tube. It is used as a control in the germinating seed experiment to provide a baseline comparison for the experimental tube with seeds.
Having the glass tube breaking all the time effects production and creates loss time for the any production unit.
Cutting a glass tube is a physical change because the cut glass tube still has the same chemical composition as the uncut tube. Nothing has changed except the physical appearance of the glass tube.
a hard glass test tube is a test tube made out of glass that is almost impossible to break.
It is a insulator. The glass does not have free electrons to flow as current, and the air in the tube is also an insulator.

It is a glass tube and it is used to contain substances being tested!

If heating continues, the water in the glass tube will eventually turn into steam and expand rapidly. This could cause the glass tube to shatter due to the build-up of pressure.
