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.
