This double children’s lecture kicks off with a curious question: What’s hidden inside a Viking’s tooth? Much more than you’d ever imagine! By studying Viking teeth, we can discover what Vikings really looked like: their hair color, their eye color, and even what they liked to eat. After that, fire safety specialist Katrien takes the stage to talk about “dangerous substances.” What makes something dangerous? Are there harmless substances too? Expect chemical and physical puzzles, real flames, and super-cool gear (water cannons! foam! awesome meters! gas suits!). And… can farts be deadly?
