Will my 6-year-old follow it?

The listing puts it at older school kids, 9 and up. It is a live talk about how materials change at very low temperatures, including superconductors, so a younger kid may enjoy the fog and lose the thread.

Do adults get anything out of it?

Planetum bills it for kids and adults, so it isn't pitched only at children.

What you need to know

Talk-led, listed in Czech, no English session is mentioned, so check your kid can follow along
Experiments, not stargazing, despite the observatory setting, so it suits kids who like physics more than planets
At the top of Petřín, so allow extra time to get up the hill before the show starts

About

A live lecture show where a presenter runs experiments with liquid nitrogen at minus 196°C. Kids see how far a chilled balloon shrinks, what happens to an LED at that temperature, whether a splash of liquid nitrogen is dangerous, and why supercooled materials can levitate in a magnetic field. Popular with school groups and the public, it suits kids curious about science who can follow a talk.
