Straw materials：advantages and disadvantages
1．Metal
Made of stainless steel，aluminum，or even titanium，metal straws have become popular.They draw some criticism for having a metallic taste and conducting heat from a hot drink，but they're strong and can be reused.
2．Paper
Paper drinking straws，which date from the late 1800s，often absorb liquid over time and can leave a taste or fibres in drinks.They're the most popular throwaway choice in places with plasticstraw bans.
3．Glass
Though glass straws may be more breakable and thus less portable than reusable straws of other materials，they hold up well to washing and reuse.Some straws are made to look artistic，with colours and blownglass designs.
4．Bamboo
This natural material can be sustainably produced and is a plantbased replacement of plastic straws.Bamboo straws are easily disposed of and turned into fertilizer.They are reusable but can be hard to clean completely and may absorb flavours.
