Kinetic sand
This sand is called kinetic because it moves easily. Kinetics is about things that move. The sand behaves like this because it has a addition of silicone oil in it. Can you see how the sand grains attach to each other, but not to other things? In addition, the sand does not dry. Can you manage to create fun shapes with the sand?
Magic sand
The magic sand is not really magical, but it is a very special type of sand. It hates water! This sand is actually water repellent, that is, it does not get wet. This is because it has been mixed with another substance that does not like water. Such substances are called hydrophobic. Oil is an example of such a substance. No matter how much you try, you can never mix oil and water. Do you know any more things that cannot be mixed with water?
