If you're not familiar with the 'QUICK RELEASE' method, read your instruction manual that came with your Instant Pot, for directions, and to make sure you know where the Pressure Valve is on the Instant Pot, and where the FLOAT VALVE is to ensure all the pressure has been released before opening the lid. Basically, you're turning the pressure valve, with a pot holder, from the Sealing position to the VENTING position, but, read the Manual for exact instructions for your model Instant Pot.
