• Sunday family workshops for kids 6 to 12, free with advance booking, September to June
• No backpacks, toys or snacks allowed inside; strollers are fine
• Best for school-age kids, since most shows are text-heavy and made for adults

Exhibitions on technology, art, and science inside the Telefónica building on Gran Vía, the city's first skyscraper. The permanent show, Exponencial, follows the leap from the first telephones to mobile phones, the internet, and AI. Temporary shows change through the year, and Sunday family workshops tie into them.
