A Twist on the Hour Glass...the Second Glass

It only takes a second for the sand to drop...I mean who has time these days to wait a whole hour? See my point?

I've actually made seven of these and they have all sold very well...sadly these are the only two I have photos for... One is made of aluminum and steel and the other is walnut.
I plan to make a few more using different materials, like various woods/like oak and cherry, as well as various plastics and metals.
