subject: Trial 1 of airlift model making

today I had some help creating a test model to see which sized pipe was best their were three different types of pipe.
Large
Medium
small
I found out that the medium sized pipe is better because there is the right amount of space inside the pipe when i use it to move sand one place to another under water.
The larger pipe was to big so it just trapped the sand inside the pipe and the small one was too compact.
