Osmosis.
Blowing over the mouth of the test tube will create a decrease in air pressure inside the tube. This decrease in pressure will cause the water in the test tube to rise up due to the higher pressure outside the tube. Ultimately, the water level in the test tube will rise as a result of the change in pressure.
Put a glass tube into the beaker of water so that it touches the bottom, then drop the crystal down the tube and put your finger over the top of the, then remove the tube gently, leaving the crystal behind in the beaker. After that laugh maniacally at the test tube and you might become an evil genius! Hope this helps! :)

the test tube has air inside it.In the outer surface of the test tube is water.Due to the different media across the test tube surface the reflection of light occurs through the glass surface.Hence the test tube shines(behaves)like a mirror
A solvent.
sprouts will grow from the potato tubule and grow more potatoes..... weird huh?
You just might get some CO2. (That's a gas.) The yeast cells will ferment the glucose in to ethyl alcohol and Carbon dioxide. The CO2 being in the gaseous form will diffuse in the atmosphere and in the test tube, ethyl alcohol in diluted form with water will be found.
can protein (albumin) diffuse out of a dialysis tube and why
When sugar dissolves in water, it occupies space within the water molecules, leading to an increase in volume. So, if you dissolve a half test tube of sugar into a half test tube of water, the volume of the mixture will be greater than the sum of the individual volumes of sugar and water, resulting in a full test tube.
One alternate wording is At waters freezing temperaturethere are 3 test tubes, cold water is in test tube A, hot water is in test tube B, and salt water is in test tube C. Which test tube at (32 degrees) which will freeze the fastest? i hope i helped!
It depends on what size test tube you are using.
Ya... In a test tube add some aluminum foils and some amount of NaOH... Introduce the flame near mouth of the test tube... Then see the magic...
