Cut the Plate

Poke a small hole in the plastic plate with a sharp knife or other pointed tool.
-
Insert the blade of your knife into the hole, and carefully saw a straight line in the plate.

Reverse the direction of your knife, and saw a straight line in the opposite direction.
-
Insert your knife in the center of your starting point, and saw outward at a 90-degree angle from your original cut.

-
Insert your finger between the cuts. Grasp and pull the plate toward you. You may need to twist while pulling to dislodge the plate.
Apply Heat
-
Poke a hole in the center of the plastic plate using a knife or other sharp object.
-
Fill the pot with water, allowing liquid to get underneath the plate by traveling through the hole. The water level should be at least one inch higher than the plate.
-
Place the pot on a heat source, such as your stove, and turn the burner on its highest setting.
-
Allow the water to heat. As it heats, the plastic plate will begin to warp.
-
Remove the plate from the pot as soon as it begins to warp. Use tongs, a fork, or another tool that provides distance between you and the hot water. Leaving the plate inside your pot may cause the plastic to melt and stick to the sides of your pot.
