Your own Slime – DIY
Introduction
Clean drinking water is essential for our health. Water containing bacteria or viruses can make us very sick. Unfortunately, not everybody has access to clean water from centralized water plants. However, nearly everybody nowadays has a smartphone! That’s why we developed a small device and an app which can be used with a smartphone to kill harmful bacteria in water. It could mean that people without a clean water supply can easily disinfect their drinking water and avoid getting sick.

How It Works
The ingredients used to make slime undergo a chemical change when they are mixed together. Glue is a thick white liquid, but when mixed with borax it forms a new chemical that is much thicker … and it’s slimy! The properties of the new substance are different: both glue and borax can be dissolved in water, but slime does not dissolve in water. Slime is also more dense than water so it sinks (unless you mixed in a lot of air bubbles when stirring it). Try to study its other properties!
