Hi guys in this blog let's do an activity which gives an idea about the concept and also it will be an entertain…. This is 《part 1》 
Be sure that you are safe when you are doing all the activities 
💡The disappearing cut: 
No1: Exercise ball, a small toy car, about 1 m of thread.
Tie the thread to the car place the car on the ball and place it in front of you now holding the thread let the car role away from you.
🤩 you can see yourself how the car disappears from the field of vision since you cannot look around the corner or around the curvature of the ball this is also the case on the earth it also a sphere and his not flat. 
💡Geyser at command 
No2: role of chewing candies, (such as Mentos), a bottle of mineral water, an open area in the garden or in field.
Open the bottle of the water And place it on the ground in the open now place at least eight candies in a lose fist in such a way that you can drop them in the bottle quickly one after the other let the candies fall in the bottle and quickly move away.
🤩 water foundation Spurts out of the bottle as in geyser almost all the water flows out and the candies remains in the bottle however the excess pressure in the bottle is not caused by heat as in the case of Geysers but instead by the candies gas Bubbles accumulate on their rough surface carbonic acid can come out of the sparkling mineral water in the large quantities since the candies or heavy they remain at the bottom of the bottle and the gas Bubbles get released and rice upward the gas carries the water along with it out of the bottle. 
💡Artificial earthquake
No3: dominoes, a large under small flat board and eraser.
Place that Dominoes one above the other on the large board position the small board in such as they that it touches the larger board now press the smaller board against the larger one and at the same time move it backward repeat the activity replacing the small board with the eraser.
🤩 both the smooth boths can be more quite easily against one another and the Domino's stones remain standing if you move the board against the Rough rubber the surface rub against each other with greater friction this static friction must be overcome first then the board and the rubber can be moved but the movement is jerking the board quakes under the Domino stone fall over like houses in the earth. 
Thank you 😁
