Floating Ball Model STEM Lab Manufacturer,Supplier and Exporter in India

Product Code : SCL-MH-12487

At the heart of the Floating Ball Model STEM Lab is the real-world application of Bernoulli’s Principle. When the built-in, child-safe electric blower pushes a continuous stream of air upwards through the streamlined nozzle, it creates a localized low-pressure column. By placing the lightweight spheres into this air stream, students can observe the magical phenomenon of aerodynamic levitation—the balls remain suspended and perfectly stable mid-air. Tilted nozzle experiments further demonstrate how air velocity changes pressure, creating an invisible structural pocket that holds the ball against the pulling force of gravity.

As a trusted, pioneering name in global laboratory manufacturing, Educational Instrument India ensures that this STEM lab is constructed from heavy-duty, impact-resistant, non-toxic ABS material. The kit comes complete with modular nozzles and varying weights of suspension spheres, enabling comparative studies on mass, surface area, and aerodynamic drag. It is not merely a toy; it is a holistic, curriculum-aligned scientific instrument designed to inspire the next generation of engineers and aerospace professionals.

Key Educational Core Concepts Covered:

Bernoulli’s Principle: Visualizing how an increase in the velocity of a fluid occurs simultaneously with a decrease in static pressure.

Aerodynamic Lift & Drag: Understanding the delicate balancing act between gravity, vertical thrust, and atmospheric resistance.

The Scientific Method: Encouraging students to hypothesize, adjust variables (such as airflow velocity and sphere mass), and record consistent empirical data.

How To Use It

Follow these step-by-step instructions compiled by our team of educational experts to maximize the scientific utility of your lab kit:

Unboxing and Inspection: Carefully unpack the kit components. Ensure you have the main base unit, the USB cord, the air nozzles, and the collection of floating spheres.

Power Configuration: Choose your preferred power source. Plug the provided USB cable into a 5V adapter/computer port, or open the base compartment using a standard screwdriver to securely insert 4 AA batteries.

Nozzle Attachment: Align your chosen airflow nozzle (start with the standard wide-mouth nozzle for beginners) with the top outlet of the base unit. Twist gently clockwise to lock it securely into position.

Activating the Air Stream: Toggle the power switch located on the side of the unit to the "ON" position. You will hear the integrated micro-turbine start, creating a steady column of upward air.

Achieving Levitation: Hold one of the ultra-lightweight polystyrene spheres roughly 2 to 3 inches directly above the center of the nozzle. Slowly release your fingers. The ball will smoothly stabilize and hover mid-air!

Advanced Scientific Investigation: * The Angle Challenge: Slowly tilt the base unit up to 15–20 degrees. Observe how the ball remains trapped within the invisible low-pressure column, defying simple vertical gravity.

Mass Variable Experiment: Swap the standard polystyrene ball with the hollow PP plastic ball. Analyze how the difference in weight alters the floating altitude.

Power Down & Maintenance: Switch the unit "OFF" after use. Wipe down the unit with a dry microfiber cloth and store the spheres safely in the provided compartment box to prevent surface indentation.

Safety Information:Choking Hazard - This kit contains small spheres. Not suitable for children under 3 years of age. Adult supervision is recommended during school classroom deployments.

Frequently Asked Questions (FAQs)

Q1: What exact physics concept does the Floating Ball Model STEM Lab demonstrate?

A1: It primarily demonstrates Bernoulli's Principle and fluid mechanics. It proves that faster-moving air around the sides of the ball creates a low-pressure zone, while the ambient room air exerts higher pressure inwards, locking the ball securely inside the stream. It also highlights the equilibrium of forces between aerodynamic lift, drag, and gravity.

Q2: Can we use standard ping-pong balls if the original spheres are misplaced?

A2: Yes! This kit by Educational Instrument India is optimized to accommodate standard ultra-lightweight ping pong balls (40mm) as well as the custom calibrated spheres included in the box. Ensure that any replacement ball is completely clean and smooth for ideal aerodynamic performance.

Q3: Is the USB power source safe for school students to use independently?

A3: Absolutely. The unit runs on a 5V low-voltage DC input via USB, making it entirely safe for elementary and middle school students. It eliminates the need for direct high-voltage AC mains wiring in student lab workgroups.

Q4: Does the product come with an educational teaching guide?

A4: Yes, every package includes an extensively detailed, curriculum-aligned manual compiled by the education specialists at Educational Instrument India. It contains multiple pre-designed experiments, foundational scientific definitions, and student assessment worksheets.

Q5: How long can the device run continuously during a lab session?

A5: The high-efficiency micro-turbine is rated for industrial durability and can easily run continuously for 45 to 60 minutes. However, to preserve power and maximize motor longevity, we recommend switching the device off during periods of observation or student notation.
