Thermally activated flower for TV show Wonders of Nature

A "demonstrator"  for  TV show Wonders of Nature  built  by J. Pilch.

Question for the audience in the show was Why and how do flowers close up at night - do  they respond  to sunlight or heat ?

The artificial NiTi reinforced "flower" presented at the show responds to the heat taken from the hot water poured on the flower from the water kettel by closing without a single drop of water gets spilled over the table.
