SUMMARY

The bonding of penny stacks on a table is likely due to the application of cyanoacrylate ester, commonly known as superglue, or epoxy adhesives. Forum participants emphasized the need for more context to accurately diagnose the bonding phenomenon. The discussion highlighted the importance of specifying details when seeking assistance in chemistry-related inquiries.

PREREQUISITES
  • Understanding of adhesive chemistry, specifically cyanoacrylate and epoxy properties.
  • Basic knowledge of physical forces involved in bonding materials.
  • Familiarity with the context of chemistry forums and discussion etiquette.
  • Ability to articulate specific questions for effective community engagement.
NEXT STEPS
  • Research the chemical properties and applications of cyanoacrylate adhesives.
  • Explore the differences between cyanoacrylate and epoxy adhesives in bonding strength.
  • Learn about the physical forces that contribute to material bonding.
  • Investigate best practices for asking questions in online forums to receive helpful responses.
USEFUL FOR

Chemistry enthusiasts, hobbyists experimenting with adhesives, and individuals seeking to understand material bonding processes.

TL;DR
There were stacks of Pennies on the table. each penny was bonded so tightly, even to the desk
What may have caused this bonding

Superglue?

You will need to give a lot more detail if you want our help. Also, so far this thread seems misplaced in the Chemistry forum. It may get moved once we understand the context and details of your question.

I think that as @berkeman suggested, maybe cyanoacrylate ester ##-## and I agree with him regarding the necessity of furtherance of the specification of the question ##\dots##

Yeah but for cryin' out loud, let's don't tell anyone. I mean if we encourage him, he's just going to do it again.
