Balls Styrofoam
Product Code : LSK-CL-10043
Balls Styrofoam (SKU LSK-CL-10043) is a 100 g pack of polystyrene foam spheres for classroom and laboratory work. Students join the balls into models of atoms and molecules, or hang a single ball on thread for simple electrostatic experiments. The pack serves middle-school science, secondary chemistry and physics, and teacher-training workshops. Schools, colleges, training institutes, tender contractors and distributors can obtain it from Science Lab Supplies, which supplies the pack out of Ambala, India.
Specifications
Each fact about the 100 g foam-ball pack appears as its own row below. In short, it is one pack of Styrofoam (polystyrene foam) balls weighing 100 g in total, intended for atom models, electrostatic experiments and general model work in the lab. Ball diameters and the approximate count are stated on the quotation.

Applications and Experiments for the Styrofoam Balls
Styrofoam balls are used wherever a simple sphere is needed in a model or a charge demonstration. In chemistry they stand in for protons, neutrons, electrons or whole atoms in structure models; in physics a foam ball hung on a thread shows attraction and repulsion when a charged rod is brought near.
- Class 9 science (Structure of the Atom): Bohr-style models of the first few elements.
- Class 11 chemistry: home-made ball-and-stick shapes compared with a ready kit such as the Molecular Model Kits for Students.
- Class 8 science: charging by rubbing, with a suspended ball and the Glass Rod with Rubbing Material.
- Science fairs and B.Ed. workshops: crystal, molecule and display models.
Keep the pack away from flames and avoid solvent-based glues or paints, which dissolve polystyrene foam; water-based products are the safer choice.
Standard Scope of Supply
Each order line is one 100 g pack of Styrofoam balls. Thread, sticks, paint and charging rods are not part of the pack. An ebonite rod or an electroscope for the electrostatics lesson, or a ready-made atom model, can be added to the same quotation so the whole lesson kit is priced together.
Packing, MOQ and Lead Time
Order a single 100 g pack for one teacher's demonstrations, or several packs for a whole class; the quotation you receive states packing, delivery time and price for that quantity. Atom models, glassware and other school chemistry lab equipment in India can be quoted alongside the foam balls.
With an Importer-Exporter Code in place, Science Lab Supplies is able to ship to buyers in Bangladesh, Zambia, Rwanda, South Africa, Qatar and Sri Lanka. Tell us how many packs your class needs on the contact page, drop them into the enquiry cart beside your other items, or turn to the lab tender page when the purchase runs through a formal bid.
Frequently Asked Questions
What are Styrofoam balls used for in a science lab?
Mainly for building atom and molecule models and for simple electrostatic experiments, where a ball on a thread shows attraction and repulsion near a charged rod. They also serve for science-fair and display models.
How much does one pack contain?
One pack contains 100 g of polystyrene foam balls. The ball sizes and the approximate number of balls in the pack are given on the quotation, so you can work out how many packs a class needs.
Who supplies the Balls Styrofoam?
The pack comes from Science Lab Supplies in Ambala, India. It is not made by the company; it is supplied as a teaching consumable and can share one quotation with atom models, charging rods and electroscopes.
Can several packs be quoted for a school tender?
Yes. Send the number of packs, the delivery location and any tender specification through the contact page, and an item-wise quotation covering packing, delivery time and price will be returned for the full quantity.
