Does it seem like it's getting harder to engage your physics students, to keep them on the edge of their seats and talking about your classes for days to come?

Perhaps it's time for a few new demonstrations from QED!  We do things based on a few simple concepts:

QED designs demonstrations with impact; demonstrations that are enlightening, exciting, and unforgettable.  We believe that outstanding physics demonstrations should be the rule, not the exception.  

QED equipment is simple to operate, reliable, and easy for students to see and understand.  We pay meticulous attention to every detail of the design, and to maintaining the highest quality of materials and workmanship .

And QED goes the extra mile to ensure your satisfaction.  If you're not satisfied with your purchase for any reason, simply return it for a full refund or exchange.  Because if it doesn't meet your highest expectations, it's not up to the standards of QED.
