A test tube becomes cool to the touch.
A round science tube is commonly referred to as a test tube. It is a cylindrical glass or plastic vessel used for holding, mixing, or heating small quantities of liquid during an experiment or as a container for chemical reactions.
A test tube can be held upright using a test tube rack, a test tube holder, or a clamp attached to a stand. These tools provide stability and prevent the test tube from tipping over during experiments.
A test tube rack is typically a rectangular or circular stand with holes or slots designed to hold test tubes in an upright position. They can be made of various materials such as plastic, wood, or metal, and may come in different colors or sizes depending on the number of test tubes they are designed to hold.
A yellow, smoky flame was likely used during the experiment, which produced soot as a byproduct of incomplete combustion. This type of flame is often seen with a fuel-rich mixture or inefficient burning of the fuel.

I think the test tube rack is used to hold any amount of chemical or liquid during an experiment.
A test tube experiment is commonly referred to as an "in vitro" experiment. This means that the experiment is conducted outside a living organism or natural setting, typically in a controlled laboratory environment using test tubes or other lab equipment.
A experiment done in a test tube is commonly referred to as an "in vitro" experiment. This type of experiment allows for controlled conditions within the test tube to study biological processes or reactions outside of a living organism.
The yellow color in the test tube during an electrolysis water experiment is typically due to the presence of bromine or iodine. These elements can be released during the electrolysis process when the electrodes are made of certain materials that react with the electrolyte solution, such as potassium bromide or potassium iodide.
putting chemicals in and construing an experiment
Observations are made in a test tube.
13x100 test tubes are excellent when you need to have larger volume in a test tube. These larger tubes allow more air to touch the sample.

A test tube holder, also known as test tube clamp or test tube rack, is used to hold a test tube in place when the tube is hot or should not be touched. It allows safe handling of test tubes during heating or when conducting chemical reactions.
A test tube can be held upright using a test tube rack, a test tube holder, or a clamp attached to a stand. These tools provide stability and prevent the test tube from tipping over during experiments.
Because if the experiment being conducted in the test tube is explosive or very reactive then it can spit out stuff and this can be dangerous to your eyes or skin. so by pointing the test tube away then you won't harm anyone if anything spits out
