This video gives you a sense of how chia seeds behave when added to a beverage. The seed coat expands to form a gel, and the seeds float throughout the drink, making a refreshing beverage similar to bubble tea.
"Chia seeds are a superfood that is receiving increasing attention, in part because of the Christopher Mcdougall book, Born To Run. I get mine at PuritansPride.com They are taste neutral, so I add them to tea, and they are neutrally buoyant, which makes them really cool to look at! Each tablespoon contains a gram of Omega 3, 2.5 grams of Omega 6, and because of their amazing water-absorbency, they provide long-term carbohydrates, with no spike or letdown, and a fantastic sustained hydration. I also think it is fun to chew on them!"
