Okay this one seems to be a front runner for now. Can ut ice cubes in, in general it is supposed to be good for keeping things cold. Can get the 25-ounce one. Under $25 for that. Prime shipping. I still don't actually know how much, even roughly, Soylent ounces are required for a day's worth of calories. #Soylent #nutrition #logistics #@front_runner #pub
