My family loves having a live Christmas Tree every year. What does a live tree need to stay alive? Water! The Base I have for the Christmas Tree has a pretty good well in it, but with a live tree, it needs to be filled at least twice a day, and four or five times a day the first few days. For years, I've been using a dipstick / funnel combo to check the water level, and refill it without having to bend over and crawl under the tree. It works really well, especially when I've got presents under the tree. I've always wanted to purchase one of the external reservoirs, but I've never seen one that I've liked. This year we're leaving for the weekend a few weeks before Christmas, so I needed one to try to keep the tree alive. Read on to see how I made one.
