Alternative Solution #3

     The solution above is a mix between an ice cube tray and a maze. The purpose of this design is to fill the tanks up evenly without filling them up on one side first and then on the other side. This would prevent the tanker from tipping due to uneven distribution of weight. 

     Like the other two solutions this design would be constructed out of water-proofed wood and hot glue or caulk. Out of all the designs this one seems to be the most difficult to construct due to more indents. 

     I don't think this is a very good design because the construction would be a lot more complicated. I also don't like the design because the process of filling the tanks with the oil-like substance would take a long time since it basically has to go through a maze.

**Note: No dimensions were included in the pictures because the size of the tanker was not yet determined st this point.**
