Summary of the video Banana Peel Slip Test! - Mythbusters - S05 EP15 - Science Documentary

Executive Summary:

The Mythbusters team tackled three myths in this episode: the slipperiness of banana peels, the possibility of making homemade diamonds, and the germ transfer of double dipping chips.


  • Adam Savage
  • Jamie Hyneman
  • Grant Imahara
  • Kari Byron
  • Tory Belleci
  • Dr. Michael Franklock (UC Berkeley)
  • Dr. Kent Ross (UC Berkeley)
  • Dr. Van Romero (New Mexico Tech)
  • Dr. Russell Banks (Pathogenesis expert)

Most Important Points and Facts:

Banana Peel Slip Test:

  • The team tested the classic slapstick gag of slipping on a banana peel.
  • Initial tests with one and ten banana peels did not cause Jamie to slip.
  • Scientific tests showed banana peels have less static and kinetic friction than a shoe but more than a lubricant.
  • A large-scale test with hundreds of banana peels on a special floor resulted in Adam falling multiple times, proving banana peels can be slippery.
  • Comparing banana peels to an animal birthing agent, the peels were rated a 6 out of 9 for slipperiness.
  • The myth was deemed busted since one banana peel did not guarantee a fall.

Homemade Diamonds:

  • The team tested three methods claimed to produce diamonds at home: using peanut butter in a microwave, molten iron, and a pressure cooker with graphite.
  • All three methods failed to produce any diamonds.
  • Dr. Van Romero from New Mexico Tech demonstrated an industrial method using explosives that created industrial-grade diamonds.
  • The myth of making gem-quality diamonds at home was busted.

Double Dipping Germ Transfer:

  • The team tested if double dipping chips transfers germs similarly to putting one’s whole mouth into the dip.
  • After a failed initial test due to pre-existing bacteria in the salsa, they conducted a controlled test with sterilized chips and homemade salsa.
  • Results showed that double dipping transferred fewer bacteria compared to putting one’s whole mouth in the dip.
  • The myth that double dipping is like putting your whole mouth in the dip was busted.

Actionable Items:

  • For the banana peel test, consider using a large number of peels and a specially prepared floor to ensure safety when conducting slipperiness tests.
  • For homemade diamond attempts, consult with experts and use proper equipment to ensure safety and accurate results.
  • For double dipping tests, use sterilized chips and dips to obtain accurate measurements of bacterial transfer.

Sentiment of the Video:

The sentiment of the video was a mix of curiosity, amusement, and scientific inquiry. The team approached each myth with a playful attitude but maintained a rigorous scientific method to determine the validity of each myth. The overall tone was lighthearted and entertaining, with a focus on discovery and debunking common misconceptions.
