Abstract: A free standing liquid membrane is disclosed that can selectively separate objects based on the kinetic energy value of the objects such that either an object having a first kinetic energy value can pass through the free standing liquid membrane while retaining the membrane and/or an object having a second kinetic energy value is prevented from passing through the membrane while retaining the membrane. Advantageously, the free standing liquid membrane can remain intact for seconds to hours with multiple objects passing through the membrane.
