One or more white-haired and white-coated Doctor Einsteins perform experiments' rather randomly..
They are very realistic and do all sorts of science based tricks like making someones watch stop, a gravity trick, magnetic spoon illusion etc, in the table magic style but with a difference in that he is Einstein!.
They perform as Einstein at science conferences and parties and are very entertaining - lots of fun interaction with guests.
They carry clipboards and silly test equipment.
We highly recommend one Einstein but you may have 2 (a clone of course..)
