During Open House, you can come on down to the Phycology Lab (from phykos, meaning seaweed) and check out different red, green and brown algae. Learn about agar and carrageenan, which are polysaccarides or carbohydrates that come from algae. They are in shampoo, diet shakes, soy milk, toothpaste and even ice cream! We will most likely have some ice cream for people to see the carrageenan in the ingredients and do a taste test!
