Are the girls free to wander around and leave the building during the day?

How do girls find their guides?
There is a meeting point at the beginning and end of each workshop/discovery fair session. This will be explained in detail during the opening session in the auditorium.
What will the girls have for lunch and how is it organised?

Are there any risks associated with participating in the ETH biennial event?
All activities and experiments are conducted under the supervision of professionals. However, some experiments require the use of electricity, liquid nitrogen or chemicals, and therefore there are potential risks such as electric shocks or burns. To limit risks, it is important that girls follow the instructions provided by the activity leaders.
