Oh...just about anything really. Chemistry sets, chemicals, microscopes, slides and collection trays, scalpels, wires, electrodes, brain wave monitors, a centrifuge, autopsy equipment, a bonesaw, such things like that.

Oh and yes, please don't touch them if you see them. I don't believe your family would be very happy with me if you were to do so. Just tell Uncle Walter should you see a tray of sugar cubes sitting around, would you, dear?
