In a fun kids' quiz, various questions spark curiosity and reveal interesting facts. Eight-year-old Ben inquires about the age of the Easter Island statues, which are nearly 800 years old. Aariya, also 8, wonders why fizzy drinks make people burp; the answer is that carbon dioxide builds up in the stomach and is released as a burp. Finn, aged 9, asks why breath is visible in the cold, with the explanation being that moisture in breath condenses into tiny droplets. Sofia, 8, learns that the ostrich lays the largest egg relative to its size, while the kiwi comes close. Lastly, Isla, 10, discovers that the most venomous animal affecting humans is the box jellyfish. These questions are part of a quiz featured on the podcast "Everything Under the Sun," hosted by Molly Oldfield, who also has a series of books related to children's inquiries.
