My friends lake was frozen. So we went on the lake but we slipped every few steps. So we decided we would make rubber roller blades. I was so excited, we tested them and it was a success. We were skating for hours. Until we had to eat and go to bed. The next day there was no frozen lake there was just water. There was also little stripes of ice still left so we skated on that. Two hours later there was no ice just water. So we put on swim suits and swam. In the end we were freezing but we still had fun.
