Thank you so much

Amazing video! Clear, simple, easy to understand.
What I'm wondering now is: what happens to the "daughter" atoms that result from the neutron hitting the original atom? Are the daughter atoms able to further be split into more atoms if a neutron hits them (although that wouldn't make sense because they are already stable)? Will they keep gaining neutrons until they are unstable again and thus, make it so they can be split again?
Or do they simply not matter after the atom is split?
I'm also wondering where the neutron that splits the original atom in half comes from in the first place.

Great, clear explanation. I am using this with my physics students as an introductory video (great for distance learning during COVID-19).

I wonder if comments ! with lots of exclamation ! points ! help ! the algorithms? !!!!

DTR A-level Physics help says:

Another really nicely produced video and well presented.
Avoid saying nuclei for a single nucleus – try to avoid doing this in the exam. Much of the energy is also in the kinetic energy of the products not just gamma rays.
