Bedtime Science Story: Nuclear Fusion (ASMR)

In this ASMR/bedtime story video, we explore nuclear fusion as a reaction (the fusion of atom nuclei) and as a possible source of power. I tell you about the differences with fission, the fundamental forces that hold atoms together, why fusion of light nuclei liberates energy, what plasma is, how man-made fusion devices like tokamaks work, and many other things.
