if we use glass plate then ring's will be clear
the sound each glass makes
charles bonnet discovered glass so that people could have something to eat on or so that they can have sagnifacent on their property and the one thing we use glass for is to make our house or property look very decinet
The spreader which is dipped in the alcohol is flamed, the fire will burn off on the spreader. It is sterilized now and could be used in the experiment.
Torricelli's experiment: Spring 1644, Florence (Italy): Venue of a famous experiment: Torricelli did his experiment with quicksilver or mercury. He proved two things with this experiment: 1, Nature doesn't abhor the void (nature doesn't fear vacuum) 2, and that the air has weight: He used a glass barometric tube of about 1 m in length which was open at one end and closed at the other end. He also used a glass funnel, which was used to pour in mercury. He put the glass funnel inside the one end open glass barometric tube of 1m and poured mercury into it. He used this method to avoid the formation of any air bubbles inside or in other words, it was not to create any void inside the tube. He removed the glass funnel after pouring the mercury, and then closed one end of the barometric tube with his finger, inverted it to make the open end at the bottom and the tube was inserted into a vessel containing mercury carefully without forming any air bubbles. He found that the mercury in the 100cm tube dropped to 76cm. He did the same experiment with water. But that required a long tube. Water has a density 136 times less than that of mercury, and this experiment returned the water column at a height of 103m. This means that the height of the water column = the height of the mercury column (76cm) X relative density of water with respect to mercury (136).
The Crookes tube is a sealed glass tube that exhibits fluorescence in it after voltage is passed through the electrodes inside. It was invented in 1875 by Sir William Crookes.
Romans experimented with different shapes of clear glass lenses. This experimentation accidentally resulted in the creation of the magnifying glass.
The electrons emitted from cathode hit the glass of the tube, causing it to fluoresce.
I don't think this is right but It might be the spectrum of visible light. You know the rainbow?
That probably depends on the experiment.
William Morris - glass artist - was born in 1957.

Put something in a glass of water, and see if it floats.
It is used to see the experiment which colour is formed.
