Smelly Shoes, Rock-licking, and Homosexual Necrophiliac Ducks at the Royal Institution on Halloween Night

UPDATE, October 21: Vikash Kumar was planning to travel to London for this, but health issues intervened. During the Royal Institution event, we will pay tribute to Vikash and his co-winner, Sarthak Mittal (in their honor, if you are coming to the Royal Institution event please wear shoes). We hope Vikash and Sarthak will be able to join us at future Ig Nobel events!


In his first public appearance as an Ig Nobel Prize winner, Vikash Kumar will be at the Royal Institution in London on Halloween night, Friday, October 31, 2025. In an event called Ig Nobel Face-to-Face, Kumar and other Ig Nobel Prize winners will ask each other questions about their work.

Ig Nobel Prizes honor achievements so surprising that they make people LAUGH, then THINK.

The winners will be joined by Marc Abrahams, founder of the Ig Nobel Prizes.

The three winners who will be take part in Ig Nobel Face-to-Face:

  • Vikash Kumar, 2025 Ig Nobel Engineering Design Prize winner (analyzing, from an engineering design perspective, how foul-smelling shoes affect the good experience of using a shoe-rack)
  • Jan Zalasiewicz, 2023 Ig Nobel Chemistry and Geology Prize winner (for explaining why many scientists like to lick rocks)
  • Kees Moeliker, 2003 Ig Nobel Biology Prize winner (for documenting the first scientifically recorded case of homosexual necrophilia in the mallard duck)
