In this video we demonstrate a nondestructive concrete analysis technique called sounding, which uses a chain dragged across a concrete slab to identify hidden delamination defects below the surface.

By manually rotating the wash drum in this washing machine, the motor acts as a generator and back-feeds electricity to the electronic control system in the washing machine. This energizes the washing machine, which was off at the start of the demo. Most people find it's easier to turn the washing machine on by pushing the on/off button, but this is good for entertainment and training purposes.

Amazing trained dogs spit out treats for Master, then walk backwards and lie down!
