ScienceMan’s Experience with… Juicing?

ScienceMan’s Experience with… Juicing?

Juicing – Introduction… Why Juice? At one point or another it seems we all consider improving our eating habits. About a year ago, I reached that point myself after many years of bacon addiction and carrying around an extra 30 pounds.

Usually I just keep my mouth shut and leave anything associated with plant material to the very capable care of my wife. But I couldn’t resist asking about the hyacinths she had made bloom during the holiday season. I thought that the growing bulbs might be of use to science teachers who want a novel way of studying root systems,…
