Project S.A.P.K.B.T

This is an instructable for a ball tower that uses a small amount of parts. I called it S.A.P.K.B.T because it stands for Small Amount Part Knex Ball Tower.

    Well, i must say, like what you have done. The idea of a low use of parts is great! But the entire instructable is let down by low light pictures, and no where near enough description. You need to explain to people how to do things with words, just saying 'follow the pictures' is not enough.
