SUMMARY

The discussion centers on the optimal material for milkshake straws, comparing highly thermal conductive materials like silver with thermal resistant materials such as glass. Participants highlight that while silver offers excellent thermal conductivity, it may not be practical due to cost. Glass, on the other hand, provides durability and resistance to freezing, making it a more viable option for maintaining smooth milkshake flow. The conversation suggests that optimizing straw design is essential to enhance user experience in fast food settings.

PREREQUISITES
  • Understanding of thermal conductivity and its impact on fluid dynamics
  • Familiarity with materials science, particularly properties of metals and glass
  • Knowledge of design considerations for food service products
  • Basic engineering principles related to fluid flow
NEXT STEPS
  • Research the properties of thermal conductive materials for food applications
  • Explore design innovations in reusable straw technology
  • Investigate the environmental impact of different straw materials
  • Learn about fluid dynamics in relation to straw diameter and material
USEFUL FOR

This discussion is beneficial for product designers, materials engineers, and anyone involved in the food service industry looking to improve the functionality and sustainability of drinking straws.

Hey guys, I am new to this forum so I don't know if this is the correct place to post this thread. Anyways, I was wondering what kind of material would be better for a milkshake straw. Would a highly thermal conductive material (like silver) or a thermal resistant material (like glass) be better for keeping the milkshake flowing smoothly through the straw? I am trying to think of a way to optimize the milkshake straw since the disposable plastic ones at fastfood restaurants are either too small in diameter or they freeze up. If this isn't the right place for this thread, I'm sorry, just let me know where to post it.

If it's not homework, and I'm guessing this isn't, you don't want to post in the homework forums. There are more rules here than elsewhere. If you just want to discuss the engineering of fast food straws, I'd try one of the engineering forums.
 
A silver straw would probably be worth more than the milkshake.
