Demo jot down: #1
The plastic tablet that gets placed into the causes water to spin like a tormenta. Then when dry out ice is definitely added the starts to rotate and generate smoke, area of the drinking water goes via dark green to light green. There is probably a chemical in the dry out ice that is certainly reacting together with the universal sign which is causing the material to change colors. Hydrochloric acid solution changes area of the mix and makes that green to yellow but when you add more hydrochloric acidity then the first time the color becomes darker and finally turn purple. The hydrochloric acid responds with the answer and makes the colours change, when you add greater than a certain amount the color becomes darker.
When the tablet went into this particular it manufactured the water begin spinning. The dry ice cubes started steaming up because when dry out ice and water react they start off producing carbon gasses. Hydrochloric acid and dry ice mixed and the water did start to change shades from yellow-colored to mild green to dark green to dark blue/purple. The dried out ice began breaking into pieces and when more hydrochloric acid is added the dried ice faded into the answer.
The tablet features reaction with the water and starts jumping around. The colour of the drinking water changes once hydrochloric chemical p is added because the indication changes the range of the hues causing those to change just like rainbow colours. The solution ceases changing colors at dark blue after it has altered color several times. The general indicator most likely mixed with every one of the extra items being added to the solution to make different colors. The dry snow was in the and almost certainly steamed away and faded.
Demonstration write up #2:
My hypothesis is that, there exists a current delivered from the electric battery wires towards the pencil and it reacts with the pad lead once dipped in drinking water causing a chemical reaction which makes area change plus the currents react with the salt sulfate triggering a series of colours to be manufactured....
