Can you imagine that the drawing can float on the water? You may not believe it but it happens. let's see. This amazing Dry Erase Drawing Float on Water experiment with Just a dry erase marker is super easy and simple to try at home or at school.

Age: 3+        Time: <10min

 Safety 

1. Adult supervision.
2. watch out, kids may drink the liquid.

 Materials List

1. What makes the drawing float on the top of the water?
2. What kinds of tray else can be used in this experiment?
3. What drawing can you create, in addition to the small person?

 Scientific Description 

Dry erase inks contain almost no adhesive, which means drawings can be easily wiped away on the non-porous surfaces. When you write down, the solution in the ink will evaporate, leaving the oil materials which are insoluble in water. The leftover is less dense than water, so it can float on the top of the water. When you pour water onto a dry erase, the buoyancy force overcomes the stickiness of the ink, lifting the ink up to the surface of the water.

 Disposal 

Pour the water into the sink. Other materials are recyclable.
