Can we bring our own cake for a birthday?

Yes on the Ilusión pack, which gives you 30 minutes at a table for cake and snacks you bring yourself. The Paradox pack supplies the cake and a snack tray instead.

How big can a birthday group be?

Groups run from 11 to 20 people, and at least one adult has to stay with the children for the whole visit.

Can we buy tickets at the door?

There is a box office on site, but sessions sell out. Booking a time slot online through Fever is the safer option.

Is the museum wheelchair accessible?

Yes, apart from the Zero Gravity room, which the museum lists as the one area it cannot make accessible.

About

More than 70 optical illusions and physics tricks spread over one floor beside Plaça Urquinaona, from a Zero Gravity room to a table that serves up your own head on a plate. Kids spend most of the 75-minute route photographing each other. Three birthday packs run alongside the standard visit, two of them with a private table for cake.
