Ok, time to ice-splain

- it looks bad ass
- it tastes better since all the impurities are removed, they will not get into your drink and foul up the taste
- it will stay colder for a longer amount of time.
- Fill the tumbler 90% full of water and put it upright in your freezer without a lid.
- Let it freeze for 18-20 hours.
- Take the tumbler out and set it on the counter for at least an hour.
- it needs to thaw just a tiny amount otherwise the tumbler will not let the ice out of the vessel.
- After an hour the ice cylinder should slide out (do this over a sink, there will be very cold water involved) If it doesnt want to come out give it a little more time. The cylinder will be half clear and half VERY white.
- You can chip away the white puts with an ice pick or cut it away with a serrated bread knife.
