Feed the Fish Challenge

I found this challenge very difficult as I wasn't sure how to get the nerf bullets in the top, because they would always either go straight over or hit the container. 

I decided to try and raise my nerf gun attachment up so I could just point the gun into the top and drop the bullet in, however when I did this I hadn't read the rules well enough to realise there was a height limit. This resulted in me realising that the attachment was 170mm too high, although it did work very effectively (video of the mechanism in action - https://youtu.be/7mnbfLNHEIY)! Another problem was that it was slightly too wide. Although I did find a solution to this it didn't matter because we couldn't get the attachment below the height limit.

I then tried to modify my original design to allow the nerf gun to fire straight up. However, this didn't give me enough accuracy and I couldn't find any other way to fire into the top within the rules. This meant I ended up just pushing golf balls into the bottom of the fish tank. This was more challenging then it should have been due to the course not being very flat; this was mainly because the course had to be transported from Bill's house (one of the team members who built it) to mine, where we filmed and did the challenges.
