An easy experiment for comparing the density of some liquids (water, oil and alcohol). It's very important for understanding water's properties.

Surface tension is a characteristic of each liquid. In this video we analyze the tension of water.

The 13th of March, our students have visited the Liceo "G.Galilei". Here our students have been inserted in a school-job project. 3 students of the Liceo (18 years old) have explained to our students what they are doing and we have experimented 3 different perspectives of water.

1. The PH of water 
2. The analysis of a sample of water taken from the Segrino lake
3. The electrolysis of water

Below you can see a video of the day.
