Discussion Overview

The discussion revolves around the hypothetical scenario of whether a popcorn kernel would pop if dropped from space during re-entry. It explores the conditions necessary for popping and the effects of atmospheric re-entry on the kernel.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants propose that understanding the conditions under which a popcorn kernel pops is essential to answering the question.
  • Others suggest that heat causes sufficient pressure inside the kernel, which is necessary for it to pop.
  • A participant questions whether the kernel would vaporize or burn instead of popping during atmospheric re-entry.
  • Another participant raises the concern about whether the falling kernel would achieve enough speed to generate the necessary heat during re-entry.

Areas of Agreement / Disagreement

Participants express differing views on the conditions required for the kernel to pop, and the discussion remains unresolved regarding whether those conditions can be met during re-entry.

"If You Dropped a Corn Kernel From Space, Would it Pop During Re-Entry?"

This wacky question way emailed to the magazine Popular Science insufficiently answered in Jan 2009 p.80

is it possible to figure mathematically this out without testing it
 
Astronomy news on Phys.org
First ask - under what conditions does a kernel of popcorn pop, i.e. what causes a kernel to pop?

Then ask, can a kernel of popcorn achieve these conditions during re-entry, or even in space, given the available sunlight and vacuum conditions?
 
"First ask" - I'm going to guess heat causes sufficient pressure inside the kernel.

During atmospheric re-entry it gets pretty hot. Would the kernel vaporize or just burn instead of pop?
 
Would the falling corn actually have enough speed to get hot during re-entry though?
