Crystal Bonsai Tree

Dave writes:

Have you tried this? Wrap a piece of sellotape around a microscope slide, sticky side up. Use pieces of copper wire to construct the branches of a simple tree on the sellotape. Add a few drops of about 0.1M silver nitrate. Use a microscope and computer to display the crystal growth. Call it the 'fastest growing bonsai tree in the world'. (Could someone try it and send us a picture please. R)
