1. A plain slice of pizza in New York City $3.00

   The 'Pizza Principle' holds that a NYC slice and a subway ride have cost roughly the same for decades — when one rises, the other tends to follow.

   Dyson spent about 100 million pounds developing the Airwrap, using the same tiny high-speed motor technology as its vacuums.

3. A French Bulldog puppy from a breeder $4.5K

   Frenchies can't swim and most can't give birth naturally — nearly all are delivered by C-section — yet they became America's most popular breed.

   It edged out the London Eye and Singapore Flyer as the world's tallest observation wheel when it opened — one rotation takes half an hour.

5. The entire Apollo Moon program, in the dollars of its day $25.4B

   At its peak, Apollo employed about 400,000 people and consumed more than 4% of the US federal budget — per landing, each Moon mission cost less than a modern aircraft carrier.
