In a blend of innovation and humor, two Indian engineers have received the 2025 Ig Nobel Prize in Engineering Design for inventing a UV-powered shoe rack that kills bacteria and removes unpleasant odors—a quirky yet clever solution to a problem found in almost every household.

A Funny Idea That Actually Works

The winners, Vikash Kumar and Sarthak Mittal from Shiv Nadar University, created a smart shoe rack equipped with ultraviolet (UV) lamps designed to disinfect shoes and reduce the smell caused by bacterial growth. What started as a simple curiosity about “why shoe racks smell bad” turned into an award-winning scientific experiment that earned global attention.

According to the researchers, traditional shoe racks become breeding grounds for bacteria and fungi, especially in humid environments. Their innovative design uses UV-C light—the same type used in hospitals for sterilization—to eliminate up to 99% of odor-causing microbes, keeping shoes fresh and hygienic without the use of chemicals or sprays.

The Spirit of the Ig Nobel Prize

The Ig Nobel Prize, organized by Harvard University’s “Annals of Improbable Research,” celebrates scientific achievements that “first make people laugh, then make them think.” Each year, it honors unusual yet thought-provoking inventions that highlight creativity, curiosity, and the lighter side of science.

For Kumar and Mittal, the recognition is both humorous and inspiring. Their project demonstrates how engineering can be practical, sustainable, and even funny—showing that problem-solving doesn’t always have to be serious to make a difference.

From Everyday Problem to Global Stage

What began as a classroom concept has now captured worldwide attention. The researchers hope that their UV shoe rack will inspire others to look for scientific solutions in everyday life, proving that innovation can come from the most ordinary frustrations.

The Ig Nobel Prize may not be the traditional Nobel, but for these two engineers, it represents something just as valuable—a celebration of curiosity, creativity, and the joy of discovery.
