From the inventor:
I was 12 years old and wanted to get my [tasty drink mix] in a water bottle. Friends were waiting and I needed to make it mobile. First, I tried to guide the powder into the bottle with my hand, that didn't go well. I quickly made a paper funnel to get the flavor actually in the bottle. This inconvenience inspired my young mind to think up a simple invention to make this process easier. Yeah, then I forgot about it.
Several years later, I was on my first deployment where all drinkable water comes in bottles. I found myself in a similar position almost daily and it didn't take long for my childhood idea to surface. I applied for U.S. and European patents and they have been approved.
Now we have a product that people are using every day to simplify a common task. Future plans involve more sizes and colors so check back for updates!
