Hello young scientists! 👋
Welcome back to Learn with Pari for Part 2 of our exciting science experiments series. Today, we have three super fun and simple experiments you can do at home using things you already have! Ready to explore the magic of science? Let’s jump right in! 🚀
🧊 Experiment 1: Ice and Thread Experiment
What You Need:
- A small block of ice
- A piece of cotton thread or thin string
- Salt
- A bowl of water
What to Do:
- Place the ice block in the bowl of water.
- Lay the thread gently across the ice block.
- Sprinkle a small pinch of salt over the thread and ice.
- Wait about 30 seconds, then slowly lift the thread.
What Happens?
The thread sticks to the ice, and you can lift the ice with the thread! Cool, right?
Why?
Salt melts the ice surface a little, and then it quickly refreezes, trapping the thread. This shows how salt affects ice and how water freezes again.
🌬️ Experiment 2: Ball and Hair Dryer Experiment
What You Need:
- A lightweight ball (like a ping pong ball or foam ball)
- A hair dryer
What to Do:
- Turn on the hair dryer to a medium or high airflow setting.
- Hold the ball above the hair dryer’s airflow (not too close).
- Try to balance the ball on the airflow.
What Happens?
The ball floats in the air, held up by the moving air from the hair dryer!
Why?
This happens because the fast-moving air creates a low-pressure area, and the ball stays balanced in the airflow. This is called the Bernoulli’s Principle.
🏓 Experiment 3: Flying Ping Pong Ball
What You Need:
- A ping pong ball
- A plastic bottle or a tube
- A hair dryer or a fan
What to Do:
- Place the ping pong ball on top of the bottle opening or tube.
- Turn on the hair dryer or fan and blow air upwards through the bottle/tube.
- Watch the ping pong ball float on the air!
What Happens?
The ping pong ball stays “flying” in mid-air, balanced on the air stream.
Why?
Similar to the ball and hair dryer experiment, the airflow keeps the ball suspended by balancing air pressure and gravity.
🌟 What Did You Learn?
- Salt melts and refreezes ice, making the thread stick.
- Airflow can hold light objects up in the air.
- Science can be fun and surprising!
