The Water Filter includes 3 natural science games with which your child can experiment with one of the great challenges of humanity filter dirty or salty water and turn it into drinking water to consume safely.

Your child will also experiment with the distillation technique, so used today in many processes and will be able to see for himself how it works and what it is for. The kit also includes a solar pasteurization experiment, which is the technique that castaways use, along with distillation, to be able to drink sea water. And with the help of an adult this Water Filter contains still many more experiments filter using only one type of filter, mix different liquids to dirty the water and try to clean it, make a solar still, etc.
