Halo Smart Bottle / Smart cooling and vacuum bottle

The Halo smart bottle is a next generation water bottle. It can cool down boiling water to just 55°C and keep water warm for more than 3 hours. Also, the Halo smart bottle has got a smart cap; when you touch the top, it immediately displays the temperature range with the different colors of halo. Thanks to this color-temperature system, you'll never need to scald your tongue testing the temperature of water. The cap can also monitor the amount of water the user drinks, showing this on its app to help people build healthy drinking habits.
