Fake Magic science show (in Finnish)
Heureka’s very own Vale Taikuri challenges the audience to ponder the differences between magic and science tricks. In keeping with the tradition of magic, we won’t reveal how the tricks are done, but we will, of course, give you some clues. Heureka’s science experiments are just as astonishing as ‘magic’, but there is always an explanation for them. As well as entertaining, the show aims to reduce our susceptibility to being deceived.
Fake Magic science show performances take place during the day in the auditorium at 11.00 and 12.00, lasting approximately 30 minutes.
Tutkija Pii’s science shows (in Finnish) feature fun and spectacular science tricks as well as zany inventions. The audience’s attention, enthusiasm and engagement with the show are guaranteed.
Researcher Pii will be performing in the auditorium at 14.00; the show will last approximately 30 minutes.
TEK has its own café next to the auditorium at Heureka, where you’re welcome to help yourself to coffee or tea, bottles of water, juice pouches for children and snack bars. You’ll also find the TEK stand at Heureka, where TEK staff will be on hand to answer any questions you may have about TEK. Do pop by the stand – you’ll receive a surprise gift!
