One of the best ways to learn how something works is to see a functioning model of it.  This month’s How It Works tour will show visitors how stationary steam engines work by operating a series of model steam engines using compressed air.  Many depict engines that rarely survived in full size, such as oscillating cylinder engines and a walking beam engine. Also present will be a newly acquired cutaway model engine that allows the interior parts to be seen in motion.   This may be the only time this year that certain pieces normally kept in storage will be brought out and demonstrated.

Admission for this special “How It Works” tours is $5 in addition to regular museum admission.
