Was OK. Looked like students science projects. (circuit boards and wires sticking out) students were on hand to explain exhibits in detail. some technical things not working, hight of some exhibits too high for 9 yr old couldn't see in.(health and safety couldn't get step, had to duck in and see it, in trying to assist 9 yr old, older child got nasty bang to head) Also he couldn't try on visual head set. (As no research as to how would effect kids eyes.)
