Globo vs. balón
While both globo and balón can refer to round, inflatable objects, they are not interchangeable. The key difference lies in their material, durability, and most importantly, their purpose.
Globo
A1A globo is a lightweight, often decorative object made of a thin, flexible material like latex or foil. It is inflated with air or a gas like helium and is primarily used as a toy or for party decorations. The term also extends to mean a hot air balloon (globo aerostático) or a speech bubble in a comic strip (globo de diálogo).

Balón
A2A balón is a durable, heavy-duty ball used specifically for sports. It is designed to be kicked, thrown, or hit in games. A balón is made of robust materials like leather, synthetic leather, or thick rubber to withstand the rigors of athletic activity.

Summary
In essence, the difference is function and material. Use globo for a light, decorative party balloon, a toy balloon, or a hot air balloon. Use balón for a sturdy, heavy ball designed specifically for playing sports like soccer, basketball, or volleyball. Think decoration (globo) versus sport (balón).
