“Nothing is what it seems. Especially in Athens.” That’s the motto of the Museum of Illusions, Athens’ headtrip headquarters for toddlers and grown-ups alike. During this May, it’s beagle mind tricks over at the two-storied museum, as Snoopy will be the star of the show every weekend of the month. The museum already displays more than 40 fascinating illusions that mix fun, awe and learning, so a Snoopy-themed collection urging toddlers to “rest this afternoon” sounds like a blast. Complementary merchandise will also be up for grabs.
