M; Do you carry a bottle with cold drink when you go outside?
F; Yeah…I take a stainless bottle in my bag.
M; What do you have in your bottle?
F; Almost cold brown tea with much ice cubes, especially in summer.
M; I see. Do you remember when you cheered your kids playing soccer games, what did you bring for them?
F; Oh…well. Our soccer parents team took turns to bring 2L sports drink bottles frozen in the bag. It would melt gradually to supply kids cold drink.
M; Didn’t you take sports drink in your stainless bottle?
F; Maybe I did…but what’s wrong?
M; It says that sports drink such as ion supply is acid water so it shouldn’t be recommended to fill in the stainless, aluminum or copper bottles because acid might melt the metal. It would cause harm.
F; Oh…really? It’s better to use frozen plastic bottle each time…but it will be wasteful and garbage problems😟
M; Better safe than sorry 😐
