Who knew that a sprinkle of salt could have such an effect!?
This man has a neat trick for collecting razor clams on the beach. Razor clams burrow under the sand when the sea is low, leaving small holes in a figure-of-eight formation on the surface.
There's no point trying to dig them out as they'll just bury themselves even more deeply. To make them come out, you just have to take some salt with you, which you can sprinkle just above the place where they are hiding.
The razor clams will then believe that the sea is rising and rush up out of the sand! Watch the video to see this in action!
