Did you remember to drink your water? Better yet, did you take a water bottle with you while you were doing your errands?
I always forget to put a water bottle in the fridge and I really don’t like the taste of lukewarm water.
So to get cold water in fewer than 10 minutes, fill up a water bottle, close it up, wrap it with a wet paper towel, and stick it in the freezer for 10 minutes.
You’ll have a cold water bottle to take with you.
