One of The You Tube Channels I subscribe to is Ondo Studio.  It’s a Channel that shows variety of simple yet very clever projects you may not see any where else.  The Channel is not narrated so it sometimes takes a couple of looks to see all that is happened.  Any way check them out at the link below.  Let me know if you want to hear of additional You Tube channels channels or particular  projects of ONDO STUDIOS.
