Since at least 1939, the year Verna Hills is credited with first publishing one of the 20th century’s most enduring children’s tune, toddlers have learned that the wheels on the bus go round and round.

We also dig into whether there is a difference between a spiderweb and a cobweb, and explore how a popular 17th century English dessert gave one of this area’s quirkier geological features its name.
WATCH: Answering your questions — from cobwebs to puddingstone
