Actually, I do have a pump.  It was built for the air conditioning 
industry but works as well as a lab pump at getting down to very low 
pressures.

I would dearly love to build a fusor!!!  Ethan and I started talking 
about doing that but then he had to move away.
However, I do not know how to blow glass.
