Programme subject to change
We do our best to guarantee the programme for the day, but very occasionally it may change. Except on school days, you will always be given the final programme at the counter.

Humidity level too high?
Our Van De Graaff generator is incredibly good at generating static electricity, but unfortunately not under all conditions. When the humidity level is too high, the static electricity flows away through the water droplets in the air.
If this happens, we will treat you to the demonstration ‘De wolkenmaker’.
On schooldays
On schooldays, we mainly receive students. On these days all expos and zones are open and you get to witness amazing science demonstrations at regular intervals. However you cannot attend any shows.
Arrive in time for our shows
There’s room for 150 visitors in our auditorium, but unfortunately that’s not enough on very busy days. We do our best to present our shows as many times as possible.
Quiet moments
If you want to visit when it’s quiet, consider visiting on a Wednesday or during weekends when the weather is nice. It is also usually very quiet on school days from 3 to 5 p.m. (closing time).
