Week 6 Lab update

Today we put formed alginate beads and submersed them into a basic solution of sodium hydroxide and distilled water. Bubbles and what looked like fuzz surrounded the beads of gel, which lead us to believe that some caffeine dissolved from the gel. For next week, we will bring better lab equipment (more distilled water, spoons, clear cups) and food dye so that way we can see the caffeine leave the gel into the solution.
