PML Adjustable Density Foam
Below is a photograph showing the results of adding various amounts of water to the mixture of foam. The difference of just adding one drop of water is dramatic. Keep in mind that if you double the batch size, you will need to double the water amount to achieve the same expansion ratio. A little experimentation is highly recommended before actual use in your project.
