Ok maybe not yet, but this is a good way to stop people from asking you whether the cup is half full or empty. Alternatively, on days you’re feeling down pessimistic, you can remove the inner top cup and have a half empty glass of drink and on optimistic days, make it half full. Alright so it’s pretty useless, but you can’t deny it’s a smart idea especially on days you want to drink half a glass of water…
