  • If you’re heating something with a lot of steam, like rice, be sure to poke holes in the top of the styrofoam cup. This will allow the steam to escape and prevent the cup from bursting.
  • Be careful when removing the styrofoam container from the microwave. The container may be hot, and the food may be boiling. Always use oven mitts to remove the container.
  • Let the styrofoam cup or plate cool down before handling it. The heat from the food can cause the styrofoam to melt or become deformed.

The best way to avoid this is to heat the coffee in short intervals and stir it between each one. You should also keep an eye on it so that it doesn’t start to boil over.
