It is actually a pineapple. The organisers didn't have time to have a cup specially made so they bought one that had already been made and for some reason it has a pineapple on it.
It is not a ball but rather a pineapple
Putting a lid on a cup helps to keep it hot by reducing heat loss through evaporation. The lid creates a barrier that traps the heat inside the cup, maintaining the drink's temperature. Additionally, the lid prevents heat from escaping through convection as well.
Boil it with a cup and a lid on. Boil it for 10 minutes and open the lid. The water droplets under the lid will be colourless
In a plastic cup, either with a plastic lid or a peel-off aluminum foil lid.
Yes, it does. I have a whole set with that size lid and the 1 3/4 cup casserole is included and the lid works.
hold a cup to your but then put lid on cup then thorw it out...=D your welcome
No, I don't believe you can because there is a wax coating on the inside of the cup that makes it so the cup won't leak.
EBAY
This is called a Ciborium
you drink it through the opening in the middle of lid with your lips open and tipping up the cup
To make a styrofoam calorimeter, you will need a styrofoam cup, a lid for the cup, a thermometer, and a stirrer. Cut a hole in the lid to insert the thermometer. Fill the cup with a known volume of water and record its initial temperature. Place the cup in a larger container filled with water and heat or cool the water to a desired temperature. Place the lid on the cup and stir the water to ensure even temperature distribution. Record the final temperature of the water to calculate the heat exchange.
A cup of tea loses heat faster without a lid because the heat energy in the tea is transferred to the surrounding air more quickly due to convection. A lid helps to trap the heat within the cup, reducing the rate of heat loss to the environment.
