I just read about the Hindu Plant Growth effect in Tarbell. I am wondering where I can get the small and large tree involved in this trick? No store I've contacted so far seems to have it or even know what I am talking about. I know it was written decades ago but Tarbell says that all paraphernelia used in this effect can be supplied for use. Any help would be greatly appreciated. I hope somebody can point me in the right direction because this sounds like a beautiful effect!
Thank you!

I don't think you are going to find that anyone is making exactly what Tarbell describes.
More than likely Tarbell was selling them to make a bit more money from his students.

But,,, I would contact Richard Hughes's http://www.hughesmagic.com
He is also here on the forums,

I am sure he can make what you need for you.

Thank you so much Bill. I really appreciate you input and I will be contacting Mr. Hughes shortly.
