Galileo Galilei and the Great Leaning Tower Disaster
Two falling balls, crushed cabbages, a confused telescope, four suspicious flies and one very powerful mother turn Galileo’s scientific experiments into a wonderfully chaotic adventure.
Cabbage safety inspector
A brilliant thought goes missing
One morning, Galileo Galilei woke up with a brilliant idea.
Unfortunately, he had forgotten what it was.
He searched under his pillow, inside his shoes and behind the curtains.
His assistant, Marco, entered the room.
“Sir, what are you looking for?”
“My brilliant idea.”
“Did you write it down?”
“Yes.”
“Where?”
“That is the second thing I have forgotten.”
Suddenly, Galileo spotted a piece of paper stuck to his back.
Marco read it aloud:
Galileo gasped.
“Of course! Today, we shall study falling objects!”
Marco looked worried.
“The last time you studied falling objects, you dropped a watermelon through the neighbour’s roof.”
“That was not a mistake,” Galileo said proudly. “That was unexpected scientific progress.”
“It landed in his soup.”
“And proved that soup cannot support a watermelon.”
Previous experiment result: The neighbour’s soup failed the watermelon-support test.
The most suspicious equipment bag in Pisa
Galileo collected two balls—one heavy and one light—and placed them inside a large bag.
He and Marco walked towards the Leaning Tower of Pisa.
When they arrived, Marco stared at the tower.
“Sir, why is the tower leaning?”
Galileo examined it carefully.
“Perhaps it is tired.”
“Should we let it sleep?”
“No. We shall climb it.”
As they entered, a guard stopped them.
“What is inside the bag?”
“Scientific equipment,” Galileo replied.
The guard opened the bag and saw two balls, a sandwich, four apples, a rubber chicken and a frying pan.
The guard raised an eyebrow.
“Which of these is scientific equipment?”
Galileo pointed at everything.
“All of it, depending on how badly the experiment goes.”
The scientist-survival experiment
After climbing hundreds of stairs, Galileo reached the top of the tower.
He was completely exhausted.
Marco asked, “Are you ready to begin?”
Galileo bent over, breathing heavily.
“First, I shall conduct an important experiment.”
“What experiment?”
“To see whether a scientist can survive climbing this tower.”
“And the result?”
Galileo collapsed onto the floor.
“Further research is required.”
A crowd gathered below.
Galileo stood at the edge of the tower and held up the heavy ball and the light ball.
“My friends!” he shouted. “Some people believe that heavy objects fall much faster than light objects.”
An old man in the crowd shouted, “Who are you?”
“Galileo Galilei!”
“What are you doing up there?”
“Science!”
The old man turned to his friend.
“He is going to throw things again.”
Galileo raised both balls.
“I shall drop these objects at the same time!”
Marco looked over the edge.
“Sir, perhaps we should check whether anyone is standing below.”
Galileo looked down.
The crowd immediately moved ten metres backwards.
“Excellent,” said Galileo. “They understand science.”

Press the button to release the heavy and light balls together. Press it again to reset the experiment.
The experiment lands in the vegetable market
He released the balls.
Both fell towards the ground.
They landed almost together.
Galileo jumped excitedly.
“Did you see that?”
A vegetable seller shouted, “Yes! You crushed two of my cabbages!”
Galileo called back, “But we discovered something important!”
“You discovered my bill!” the seller shouted.
Galileo hurried down the tower.
When he reached the bottom, the vegetable seller handed him a damaged cabbage.
“Explain this.”
Galileo examined it seriously.
“The cabbage has changed shape because of force.”
“It has changed shape because you dropped a ball on it!”
“Exactly! You understand physics!”
The seller chased Galileo around the tower with the cabbage.
Galileo ran while shouting, “Science is not always appreciated immediately!”
The Moon, the neighbour and four suspicious flies
Later that evening, Galileo looked through his new telescope.
Marco stood beside him.
“What can you see?”
Galileo adjusted the telescope.
“I can see the Moon.”
“Wonderful!”
“I can see mountains and craters.”
“Incredible!”
“I can also see our neighbour waving angrily.”
Marco looked confused.
“Our neighbour lives across the street.”
Galileo slowly lowered the telescope.
“I may be holding it backwards.”
He turned the telescope around and looked again.
“Now everything is much closer!”
“What can you see now?”
Galileo gasped.
“Jupiter!”
“Can you see its moons?”
“Yes! One, two, three, four—”
Marco looked through the telescope.
“Sir, those are flies sitting on the lens.”
Jupiter finally appears without flies
Galileo cleaned the telescope and tried again.
This time, he really saw four moons orbiting Jupiter.
He became extremely excited.
“The Earth is not the centre of everything!” he cried. “Some objects travel around other planets!”
Marco nodded.
“So the entire universe does not revolve around us?”
“Exactly!”
At that moment, Galileo’s mother entered the room.
“Galileo! You forgot to wash the dishes!”
Galileo whispered to Marco, “Although in this house, everything still revolves around my mother.”
An orange, a rubber chicken and twelve unfortunate plates
The next day, Galileo decided to demonstrate the movement of the Earth.
He placed an orange in the middle of the room to represent the Sun. Then he walked around it while spinning.
“The Earth rotates and also travels around the Sun!” he explained.
Marco watched him circle the orange faster and faster.
“Sir, you look dizzy.”
“Nonsense! I am demonstrating astronomy!”
Galileo spun again, stepped on the rubber chicken and crashed into a cupboard.
The cupboard opened, and twelve plates fell onto the floor.
Galileo’s mother ran into the room.
“What happened?”
Galileo stood among the broken plates.
“The Earth moved.”
His mother pointed towards the broom.
“Now Galileo will move too—towards the cleaning cupboard.”
Law of household motion: A scientist surrounded by broken plates will move rapidly towards the cleaning cupboard.
Galileo records the day’s most important discoveries
That night, Galileo wrote several important observations in his notebook:
Galileo’s Important Observations
Observation One: Heavy and light objects fall almost together.
Observation Two: Cabbage sellers dislike physics.
Observation Three: Jupiter has moons.
Observation Four: Never spin near expensive plates.
Observation Five: The Earth moves around the Sun, but Galileo moves wherever his mother tells him.
Years later, Galileo became famous for changing how people understood the universe.
However, the people of Pisa remembered him for another reason.
Whenever Galileo walked near the Leaning Tower, every vegetable seller immediately covered the cabbages.
