How much are tickets for the kids' day?

Booked online in advance, it's €16 for kids 5 to 17 (and discount groups) and €23 for adults over 18. At the door it's €19 and €26, so booking ahead saves €3 a ticket.

Does a regular ticket get us into the adults' night?

No. The H18 night sells its own tickets in Heureka's online shop, and it's only for over-18s.

About

Heureka, the science center in Vantaa, does Halloween over two days. The family day is the one for kids: they make masks, paint monsters and visit the dinosaurs, and dressing up is welcome. The evening before is an adults-only H18 night with a lizard theme. It suits parents planning a night out, not a family trip.
