The Tasting Bottles material helps to develop the sense of taste by recognizing and matching solutions with different flavours. The set includes eight small glass bottles with eye-droppers and a wooden tray. The bottles are made of brown glass so that students cannot identify the liquid inside by its colour. Each bottle has a glass eye dropper with either a white or black silicone squeeze top for transferring the solution to a spoon or dropping it directly onto the student's tongue. Fill pairs of white and black bottles with the same solution, and then have students identify matching pairs by their taste only. We recommend hand-washing both the bottles and the eye-droppers after each use rather than putting them through a dishwasher.
