I may be wrong, but I don't think there are any such items in the ep that will allow a non-magician sim to perform magic tricks, unfortunately.
From my personal observations, the hidden skill that unlock the tricks at the various levels seem to only appear and rise solely in conjunction with sims in the magician career, though when my magician sim quit at the top of his career, he got to keep the 'Box of Mystery' stage prop though he lost the entire series of 'Magician...' interactions that usually appears when I click on other sims while playing him (when he was still working as a magician). I haven't tried it myself, so I'm not sure if the 'Box of Mystery' stage prop can still be used to perform tricks by non-magician sims, but I did read on the guide that sims can perform the 'woohoo' interaction with it.
