The right amount of info for a product website?

I am working on putting together a kickstarter campaign for my coffee press/travel mug invention (www.pascalpress.ca). I realize it is not the most intuitive process and .gif may not be enough to explain the process fully. I want to keep my website clean and minimal while still providing enough info to consumers as to why my product is better than others on the market. Would an embedded 'how-to' video or an 'About' page with text be more effective to explain my product?
