Why do coffee cups have saucers?
It’s standard practice in the industry to serve coffee with a saucer, for reasons like convenience and neatness. It’s a clean place to rest the spoon, it’s a stabilizing way to carry the cup and catch drips, and it’s a sharing plate in case your friend shows up and wants to some of your pastry.

What happened to the water in the jar when you added more one peso coins?
As we add coins, the amount of water spilling over the edges is getting larger and larger until the water just can’t take it anymore! Gravity is pulling on too many of the molecules for their attraction to keep them up, and the water spills down the side of the glass.
What happens when you put a penny under a glass of water?
When the cup is filled with water, the penny disappears. This happens because of refraction. When light bounces off of an object, it reaches our eyes and we see the object. As light travels through the sides of the glass and the water, it’s refracted and never reaches our eyes, which makes the penny seems to disappear.
Why does the water spill out when you tilt the jar to the side?
The card stays on the upside-down jar because the pressure of the air molecules pushing up on the card is greater than the weight of the water pushing down. If you tip the jar at all, air will come into the jar and break the seal, causing the water to pour out. Tip the jar sideways and the water falls out of the jar.
Why does a penny hold more drops of water than alcohol?
But alcohol has a different size and shape and has its polar part on one end. Alcohol molecules can meet at areas where they would not attract as strongly. The water is more attracted to itself than to the metal of the penny. The alcohol is a bit less attracted to itself so it spreads more on the penny.
How many drops of water will fit on a penny?
Were you surprised to discover that a lot more drops of water fit on a penny than you predicted? We had 27 drops of water on ours! Surface tension and cohesion is the reason you can get so many drops of water on a penny. Cohesion is the “stickiness” of like molecules to one another.
How many drops of cooking oil can fit on a penny?
To help ensure the best results, we used a clean penny each time. Our results were interesting. I knew that the oil should have less surface tension than the water, but we had equal results – 23 drops for each.
How many drops of isopropyl can fit on a penny?
The number of drops that the students can put on the penny will vary from about 30 to 50 depending on size of drops.
Does water or isopropyl alcohol have a higher surface tension?
Surface Tension of Water (at 20°C) = 72.8 mN/m Surface Tension of Isopropyl Alcohol (at 20°C) = 23.0 mN/m (Note that the actual surface tension of rubbing alcohol will be slightly higher than the value for pure isopropyl alcohol, because rubbing alcohol is 70% isopropyl alcohol and 30% water.)
