The sorcerees are perfecting their liquid magic tricks. The girls must make a drink appear as if from nowhere, whilst the boys have to switch liquids and transform them into something solid. In their final lesson before their next performance, Mr Knight decides to test the boys ability to deal with an unfriendly crowd. Scottish lad Michael gets into difficulty when his fellow sorcerees try their hand at heckling. To help shape their tricks into all round routines, dramatic arts teacher Miss Roberts gives the sorcerees a lesson in stage presence, but for nervous Holly becoming a confident performer is proving a tricky business. During the dress rehearsal even magic ticket winner, Tommy, is having trouble. Once again, the magic teachers wage their own war in another round of Teacher Challenge. Who will come out on top in liquid magic?
