Overview

Tom Scott hosts a lateral thinking puzzle show featuring three guests from the Lunchbox Envy podcast: Manu Onrio, Jack Chambers, and producer Alex Bell. They tackle food-related brain teasers ranging from tachographs and fruit bats to hockey jerseys and corporate security donuts, demonstrating creative problem-solving through wordplay, logic, and unexpected connections.

Introduction and Tachograph Puzzle

The episode opens with Tom Scott welcoming the Lunchbox Envy podcast team and diving straight into a puzzle about truck drivers. The guests work through clues about law enforcement, steering wheels, and rest requirements before discovering that 'taco' refers to a tachograph - a device that records driving hours and speeds. The conversation reveals how these devices evolved from circular paper records with graphite markings to modern digital credit card-shaped logs.

  • TACO is short for tachograph, a legal requirement for truck drivers that records driving hours
  • Tachographs evolved from circular paper records with graphite trackers to digital credit card devices
  • Police can use tachographs for forensic analysis after accidents to determine speed and driving conditions
" If it was really bad, the graphite would just write out, shit! "

Lunchbox Envy Podcast Overview

The guests introduce their podcast Lunchbox Envy, which explores the weird and wonderful stories behind everyday foods. They discuss recent episodes including apple research involving Newton's famous tree, and share the bizarre 'cube rule' theory that classifies all foods into six categories based on where structural starch appears. The conversation reveals both the culinary expertise and playful approach the hosts bring to food history.

  • Lunchbox Envy explores strange stories behind everyday foods with hosts Manu, Jack, Rosie McKean, and producer Alex
  • Alex visited the actual tree where Newton saw an apple fall, which still produces fruit and has cuttings sent worldwide
  • The 'cube rule' classifies foods based on structural starch placement: pizza and cheesecake are both 'toast', while calzones are type six
" We eat so well every time we record. "
