For 10 euros, you can wander down in the the basement of cafe strudel located within the grounds of the Schonbrunn Palace (free entry to the grounds) and enjoy seeing one of the employees twirl pastry around with great flair and explain the basics of strudel making (which aren't actually all that basic and seem to require a great deal of skill). You also get a piece of strudel and a tea/coffee/cold apple strudel flavoured drink (very highly recommended!).
