Rumour has it that living dinosaurs have been spotted at the science centre

Just rumours… or are they? If you hear an alarm during the evening, stand still and remain quiet if you are in a queue. Otherwise, find a safety zone marked with tape on the floor and stay there until the alarm stops.

Pre-party at the Science Restaurant from 5:45 PM

The pre-party costs €23 per person, including a special tapas menu, a keynote talk by Vili Koskinen (in Finnish) and priority entry to the H18 event. Event ticket purchased separately.

Tervetuloa salaiseen tiedekeskukseen!

What happens inside the building next to Tikkurila station after dark? Would the experiments conducted there stand up to the light of day? And could the rumours about living dinosaurs be true? Surely not… but you never know.

Welcome to the science party of the year! Take part in memorable workshops, hear fascinating talks and explore Science Center’s exhibitions in the company of other adults. Scroll down to see what’s happening throughout the evening!

Workshops

Beer brewed with murder water – come turn it into sorbet!

Come make beer sorbet using Fat Lizard’s Lake Bodom beer! At the start of the workshop, Fat Lizard’s experts will explain how the beer is made. You’ll also get to see the “murder water” brought from Lake Bodom.

Workshop note: Places in this workshop are limited. Arrive early to secure your spot.

Synsepalum dulcificum (The Miracle Berry)

Have you heard of the miracle berry? It contains a glycoprotein called miraculin. What makes this berry special is that, after you eat it, foods that normally taste sour or tart taste sweet instead. We challenge your tongue and brain!

Do you have a predator’s instincts, or are you easy prey?

Did you know that, through evolution, 70% of people have developed the ability to taste poisons in plants? Around 30% of people lack this ability. In this genetic taste workshop, find out which category your tastebuds fall into.
