The realistic design of model water bodies is no longer a witchcraft. The Water-Drops are simply heated in a heat-resistant container (such as a jam jar) at 170 °C for about 30 minutes in the oven. After the drops melt, the material remains liquid in a syrupy consistency for about 2 minutes. Now it can be poured calmly into the prepared stream or lake bed. Once the water in your model landscape has hardened and you wish to make further changes to the water surface, it's no problem: you can melt and rework the surface at any time with a heat gun. With a standard hairdryer, you can even re-liquefy the entire Water-Drops water body.
