Do GMO Plants Sing?

This is an experiment conducted by Alexandra Christ. She bought two similar tomato plants, one was GMO. Next she connected a device invented by the Damanhur Community in Italy to the leaves. This device will translate the electrical impulses of plants into music. It is called the "Music of the Plants Machine!" Let's see what happens in this duel of the GMO vs. non GMO plants!

Same as if a human were to play the same song on various different types of guitars or pianos.
