It is difficult to write things down when you are in the swimming pool, Jacuzzi, sauna or hot tub, but when you are relaxing or exercising it is common to have thoughts and ideas. It is impossible to write the ideas down on paper when you are wet. However the waterproof memo boards are ideal in this situation as they are fully water resistant. You can jot down anything from ideas for work to plans for a party even your shopping list.
