Press the bar of soap firmly against the plate with moistened water, and turn it several times. Lift the soap up, and the plate rises with it. Explain why this happened?

Then atmospheric pressure will press the soap against the plate so much that it will allow us to lift the plate along with the soap, applying force only to the soap.
