Want instant cool drinks but don’t want to dilute the drink with water? Then stainless steel ice cubes are for you. Just cool the cubes in the freezer as you would do with ice cubes, then drop them into your drink to chill it.
I tried cooling a full big bottle of beer and unfortunately the 8 cubes i have isn’t enough to cool it down to the 4 degrees that would be ideal for beer. Then again, maybe i did not stick them in the freezer long enough prior. It is still a good way to get instant chilling though.
The cubes are actually filled with some sort of liquid that has a lower melting point than ice, so it could be cooled down to sub-zero temperatures. The coolness (no pun intended) factor of the cubes is definitely there. If you want a cheapo alternative, you can actually find stone cubes sold at Daiso, for only S$2 of course.
