We took our two children to the ski resort for ski lessons awhile back. I was amazed to see how advanced the bunny slopes have become.
They now use a thing called the "magic carpet" to teach children how to ski. They look like a conveyor belt stretched out over the snow.
There's typically a motor running underneath the belt that pulls the student up to the top of the bunny hill and then releases them onto the snow where they just slide down the hill.
