Funny :) but it wouldn't be a real problem. The super magnets are  
quite small and just put out enough field strength to interact gently  
with things outside the concrete. Its not the same as if you put two  
big super magnets together. The reason I used super magnets is that  
they are inside the concrete by >1/4" so the magnetic field is  
attenuated (inverse squares law). I wanted them to be noticeable to  
the kids if they had anything that would be attracted yet still safe  
and secure within the concrete matrix.
