How about keeping your water bottle cold all day ?
It could be useful on a ride when it's hot, right?
Well, it is possible! Know that there is a very simple trick to drink fresh all day.
The trick is to put 1/4 of water in a bottle and put it lying in the freezer. Watch:
1. Put about 1/4 of water in a bottle.
2. Lay the bottle in your freezer overnight.
3. Take out the bottle and fill it with water before you leave.
And There you go ! You have cold water all day :-)
By the time the ice melts, you have enough to quench your thirst with very cold water.
And if you're going away for a really long time, nothing prevents you from putting a little more water in the freezer, to have more ice cream.
