Water-Bending Balloon

New Canaan CT, April 10 2019

This image demonstrates electrostatic attraction. Water is composed of one positively charged oxygen atom and two negatively charged hydrogen atoms. These atoms combine to form a neutral molecule. After the balloon was rubbed against hair, it gained a negative charge due to an increase of negatively charged atoms on the balloons surface. Wanting to return to a neutral state, the negatively charged atoms of the balloon attract the positively charged protons in the water, causing the stream of the water to bend. The water is able to bend due to the fact that it is a polar molecule. Water is a polar molecule since it is composed of both positively and negatively charged atoms, and it has the ability to bend towards attractions. This picture exhibits electrostatic attraction due to the balloon's ability to bend the water based on the object's overall charges.

8 Layers of Liquids

New Canaan CT, April 10 2019

This image depicts the density of liquids. From bottom to top, the layers are composed of honey, corn syrup, maple syrup, whole milk, dish soap, water, olive oil, and isopropyl alcohol respectively. These substances are able to remain separated due to their varying densities. Density is the defined as the degree of compactness of a substance. For example, the molecules of honey are more compacted and in turn denser than those of isopropyl alcohol, allowing the substances to remain on top of each other without blending together. However some layers, such as olive oil and isopropyl alcohol, mix slightly due to their similar densities.
