My son asked me this today, and while I thought that I had a sorta kinda basic idea (the cores don’t need to touch as it’s enough if the the electron cloud-thingies interact), I could not explain it so he could understand and neither was I sure enough of this being the correct answer. Can anyone help?

Technically it doesn’t touch. Whilst we see and here it ‘touch’, it’s still separated at that sub-atomic level by those opposing forces.
Just explain it to him that if you had a strong enough microscope (I don’t think one exists yet) you’d be able to see the gaps, and it’s actually the forces of these particles that hold things apart – similar to two magnets with the same pole.
