Beakman challenge: pour water from one beaker to another, keeping them far apart. Take yarn and dip it into on beaker and then pull the yarn tight and put the end in another beaker. The water will travel down the yard that is soaked in water due to adhesion and cohesion.
Hank explains why solid water is less dense than liquid water even though solids are typically more dense than liquids. He also discusses how the high heat capacity of water helps support life on Earth. He uses the bodily process of sweating to exemplify water's unique properties.
Phil tries to pour himself some water, but some of the water sticks to the pouring glass and spills onto his plate of food. He explains why this happens: because water likes to stick to things due to its cohesive properties. He offers suggestions to prevent water from sticking to the pouring glass, such as changing the angle at which the water is poured out.
An introduction to the properties of H2O and its components: hydrogen and oxygen. This clip also explains that water has highest cohesion of any nonmetallic liquid, which allows other substances to stick to it.
Lester is challenged to use only a piece of string to pick up a piece of ice without touching it. USing salt, he sprinkles it on the ice and wets the string and sits it on the ice. After about 2 minutes, the string is now frozen to the ice and it can be picked up. This is because salt lowered the freezing point of water and now the water on the string can freeze to the ice cube.
