use a metal container to keep a drink very full
A metal container will least insulate a cold drink compared to other materials such as plastic or glass because metal has higher thermal conductivity, meaning it allows heat to transfer more quickly between the drink and the external environment. This can lead to faster heat exchange and warming of the cold drink inside the metal container.
A polystyrene cup has low thermal conductivity, which helps to prevent heat transfer between the drink and the external environment. This insulation helps to maintain the temperature of the drink for a longer period of time, keeping it hot or cold.
You can keep a cup cold by using a double-walled insulated cup, adding ice cubes, or placing the cup in the refrigerator or a cooler. Additionally, using a coaster or a sleeve can help insulate the cup and keep it cold longer.
Styrofoam
A double-walled insulated cup made of stainless steel or vacuum-sealed material will keep drinks cold the longest by preventing heat transfer. Look for a cup with a lid to further maintain the temperature.
Of Course
styrafoam.
Moscow Mules are traditionally served in copper cups because the metal helps to keep the drink cold for longer periods of time. Additionally, the copper material is believed to enhance the flavor of the cocktail, giving it a unique and refreshing taste.
Not for long.
A Styrofoam cup will do both. The Styrofoam is an insulator, and, as such, it slows the transfer of heat between the system (the drink) and the surroundings (everything outside the cup) If it is a cold drink, heat moves very slowly through the cup toward the drink. If it is a hot drink, heat moves very slowly through the cup toward the surrounding air.
Because metal cups warm up and can burn you when you are dinking a hot cuppa
