**CHENNAI, INDIA – February 25, 2025** – A challenging science quiz published in *The Hindu* newspaper on February 21st has sparked online discussion. The quiz, focusing on unusual materials, featured five particularly intriguing questions.
The quiz tested readers’ knowledge of materials science, ranging from the lightest known solid (a material over 99% air created by supercritical freezing) to a mysterious material developed by a British hairdresser in the 1970s claimed to be heat-resistant. Another question focused on the world’s second most-used material (after water), known for its strength but susceptibility to cracking, and current research into self-healing versions.
A pop culture reference was included, asking about the transparent aluminium ceramic compound featured in the 1986 Star Trek film, “The Voyage Home”. Finally, the quiz challenged readers to identify a one-atom layer material similar to graphene, and a non-radioactive metal exhibiting unusual density properties in its liquid state.
The quiz, available on *The Hindu*’s website, has generated significant engagement, prompting readers to share their answers and discuss the intricacies of materials science. The paper encourages readers to comment on the article, provided they adhere to community guidelines.
