"CosmoCaixa is a grand, attention-grabbing science museum with five floors of exploration. The star attraction is the Flooded Forest, an epic recreation of the Amazonian ecosystem. The tree roots are vast and tangling, and—warning—the museum did not scrimp on poisonous tree frogs, crocodiles, or piranhas.There’s also a ton of interactive material for kids: robots they can control, animals they can touch (not the piranhas, to be sure), a hall of mirrors, a 3D planetarium, and more." - Gemma Askham
