The Ciutat de les Arts i les Ciències proposes simple experiments to do at home

See how a fluid can be moved without touching it simply by creating a pressure difference of pressure using a pen, a bottle of water and a dryer, or demonstrate that a sphere is the geometric shape that allows it to hold the greatest volume with the least surface area, using a balloon, paper, scissors, measuring tape and a calculator.   These are two of the simple experiments that the Ciutat de les Arts i les Ciències suggests in the section of its web section devoted to the botanic gardens in the Umbracle 

The leaves of the palm trees we see in the Umbracle react to a peculiar passive cooling system and most of the fruit has a round shape to provide better protection for the seeds. These are some of the curious things about biomimetics that visitors can learn in a 'virtual' visit to the Umbracle. This is about a discipline inspired by natural designs, processes and natural systems to develop innovative solutions in fields such as architecture or engineering.

Besides explaining an aspect, fact or reason, the files on biomimetics suggest an activity that demonstrates them. Furthermore, the buildings of the complex themselves are excellent examples of this inspiration from nature, as many of their structural details can be seen.
