Can Red Solo Cups Hold Hot Water?
Red solo cups can hold hot water if the temperature has dropped below 90 degrees Centigrade. In this case, you have to allow your boiling water to sit out for some minutes before pouring it into the cup. Let the temperature drop below 90 degrees Centigrade so the solo cup won’t become deformed.

What is a Red Solo Cup Made of?

What Temperature Do Solo Cups Melt?
The temperature that solo cups melt is 100 to 120 degrees Centigrade (212 to 248 degrees Fahrenheit). Polystyrene, the material used in making these cups, melts at this same temperature.

Another reason not to pour hot water into a solo cup is the heat. You could get burnt when you pick up the cup to drink from it.
Can You Put Hot Coffee in a Red Solo Cup?
