Kairan, a couple of weeks ago, you wanted to lean a pipe against this metal frame so that you could send sand down it, but the pipe wasn’t tall enough. What could go underneath the pipe to make it taller? A cone! You filled a cone with sand, and put the pipe on top. But the cone fell over. How to make it stand up? You, Ferdinand, and William put sand around the cone to hold it up. When it stayed up, you put the pipe in and said, Now we can play! and you and Alice and Arlo and William poured sand down the pipe.
