Stephen Hawking asks what are the building blocks of life and how did they come to be in this video. His volunteers are presented with a number of blue and yellow pentagon-shaped magnets. The individual magnets are similar to atoms of different elements, such as: carbon, oxygen, or hydrogen. They have positive and negatives charges; they can attract of repel each other. Each different combination creates a different molecule and many combinations are possible. From this example, can they piece together how the building blocks of life, such as molecules and amino acids, were first created?
