Wafer keyboard for...juice?

This video is undoubtedly awesome but I'm not exactly sure what it's for. I'm going to guess juice as it ends with strawberries and some round things in a bowl that look a little like grapes. Oh and the description has these words in it 'Açaí Juice 100% fruit'...man I wish I could speak Spanish. Anyway, there's some sweet stop motion nuggets and bright colours. Love it.
