This is a funnel that can be used for many things. I created it as a way to help guide pebble ice into a water bottle I use. It can be used for many different sizes of bottles and can be used to guide liquid as well. It's just a basic funnel. :) Here's a video showing how I designed it and what I used it for. Enjoy! https://youtu.be/g9P1sCn8D98
