A great eco-friendly invention by Coke. No need to look for trash bins to dump the empty can or glass bottle. The bottle made of ice will simply melt in your hands not leaving any bio-waste behind. You can also just eat the bottle not leaving any residual waste at all.
We can trust coke to come out with such unique things after the split in to half coke cans,
This however can bring certain scenarios in mind in a hot climatic country like ours. What if the bottle melts before you actually manage to finish the coke. Or in a cold country what if the bottle gets stuck to your lips. I guess Coke will confine itself to rolling out such bottles only in moderate climate countries.
