BAMBOO

QUESTION
I have purchased some bamboo to make a Japanese water feature that scares Herons. I have seen a bamboo tube on a pivot, which fills with water then rocks to a new position where it empties, rocking back to its original position for refill.

Any idea where I could get a design for this? I want to be sure where to cut the bamboo and where to install the pivot. Thanks.

ANSWER
Thank you for your enquiry. For best results contact an aquatic specialist who may be able to advise you on your chosen water feature. We at StyleGardens have a Japanese themed garden with a similar feature but it does not rock back and fore. If you live locally you are welcome to visit our centre so that you can obtain a visual idea of how it could work.
