Washed away 

Placed the tube on the shore break and during the 10 sec. exposure, 3 small waves moved it as recorded.
Camera was standing on my Gorillapod at aprox. 10 cm from the water ;)
GND8 + Sunset Cokin filters were used to compensate the lighting due to the long exposure.
Shot at the river bank in Setúbal - Portugal
Hope you like it, I did.

PS- I removed the tube from the water after the shooting ;)
