Since I assume the managerial position in our store , every other day I see to it that I have loads of ice water in the container. At first it was difficult to make it but when you successively make it, you will find it easy. All you have to do is to one piece of 3 by 16 cellophane, then place it in the faucet, switch it on. When the water reach before the top of the cellophane, switch the faucet off, twist the cellophane until it was sealed. Turn the cellophane to right, then slide your finger on the top, pull it to sealed the water. Easy and enjoyable task.
