Ordered a clear-ice ball maker from Lazada to review whether it really comes out as clear as the ones you see at stylish bars. Instructions say to freeze it for 24 hours.

Tried it, and it really does come out clear. Ice like this melts slower than usual. Downside: it's a bit hard to pop out of the mold, but you get ice with zero air bubbles. The ice size might not be as satisfyingly big as you'd want — will try other models to compare.
