Day 1 (4-11) Building
We utilized plastic wrap and tape to waterproof the interior of the container. We also laser cut a piece of acrylic to both reinforce the bottom of the container as well as to make the bottom of the container waterproof. This piece was attached using hot glue. We also created the connecting piece from the spray nozzle to the container by using straws, tape, and hot glue. We also drilled a hole through both the acrylic piece and the container to run the connecting straw piece through. We also began to connect the container and straw system together.
Second Prototype Container
Day 2 (4-18) Building
We created a stopper around the straw system in the interior of the container to keep it from falling out of the container. This stopper was created out of tape. The straw system was then also hot glued on the exterior of the container. We then created a wooden platform with a hole the size of the mop handle drilled through it. We then placed the wooden platform at the appropriate height on the mop handle and secured it using hot glue. The container was then attached to the platform and the handle using hot glue. The straw system length was also adjusted such that the nozzle would be positioned in the proper place.

Day 3 (4/20) Building/Testing
We attached the spray nozzle to the mop handle as well as a support brick. The spray nozzle was also attached to the straw system. A crossbar was also attached slightly above the spray nozzle for the strings to rotate about. A string was then cut to form a circle and attached to the spray nozzle. It was then placed such that it would rotate about the crossbar before running up along the mop handle to the top. The second prototype was then tested by taking it outside and adding water to the container and attempting to spray the ground. The prototype was able to spray the ground multiple times and remain intact. However, after a while there was a slight leak in the container as well as slight loosening of the crossbar. For the final prototype, we will ensure that the seams on the container are tight and switch to a pulley crossbar system to try and limit the force and thus prevent weakness.
