The kids have been having fun with our little homemade ice rink! We made a frame with 2X4 boards, laid a heavy duty plastic drop cloth in the bottom, filled with water and waited for it to freeze! The kids have had fun playing hockey on it. My husband also threw coins in the water before it froze so when it melts, the kids can collect them. We have had to add more water every few days to keep it going, but it has worked out.
