BEAKER: Hey, Test Tube! I heard that you love chemistry?
TEST TUBE: Of course, who wouldn’t? Although, I love it more when people come in the lab and play with me! 😛
BEAKER: I love it because I get to hear the conversations students make while in the lab. It’s interesting! Even today, I heard something interesting!
TEST TUBE: What is it? Tell me, Please!
BEAKER: Ummmm, Okay! Let me test you! Tell me the name of an element that needs a lottttt of space?
TEST TUBE: Duhh, that’s easy! It’s Hydrogen! It is the most widespread element in the universe! Ask me more, keep trying!
BEAKER: What happens to the volume of water when you add table salt to it?
TEST TUBE: Beaker, that’s so easy! I have ears too! Volumes are not always additive. When you add table salt, or NaCl to water, you are increasing the density of water. This happens due to positive interactions between water molecules and Na+ and Cl– ions. Since the resulting mixture is denser, the total volume will decrease and become lower than the actual sum of volume of water and volume of the added salt.

BEAKER: Okay, I bet you didn’t know that “Glass is not a solid – glass is a liquid.”
TEST TUBE: As the glass molecules flow very slowly, this means they will not shatter or change shape. Often, this state is known as being amorphous. See, I knew this too! Don’t take me lightly because of my size. 😛
BEAKER: You’re a genius, Test Tube! You should be asking me questions!
TEST TUBE: Hahahaha! Well, I’ll put you up to a test soon! Let’s hope no one breaks us before that time comes!
