Can you grow a plant upside down? Try it, and see what happens.

Roll a blotter around the inside of a glass. Fasten  it  with  gummed tape. Place  several  radish  seeds near the rim, between the blotter and the glass. Keep the water level in the glass just below the radish seeds for a few days.  The young plant “senses” that it must send its leaves up and the roots down. Why is it so important for the plant to do this? Why Do Roots Grow Down? After a few days the seeds sprout. Tiny roots start downward and small stems and leaves go upward. As soon as the leaves of one radish plant get above the top of the glass, pour out the water, turn the glass upside down, and place the rim on two pencils or strips of wood. Keep the blotter moist by adding water several times a day. Do the plants grow upside down? Not at all! The leaves turn and grow upward while the roots grow downward again. When you are hungry you go to the refrigerator and get some food. When a plant needs food there is only one way to get it—and that’s by making it. In fact the plant has the only real food factory in all the world. Our factories simply start with food that comes from plants and change it a bit to make it more digestible or tasty. The plant is such a good food factory that scientists have not yet been able to make food the way a plant does.  What does a plant need to make its food?  You can find out by doing some experiments  Radish seeds are excellent for these experiments. They sprout quickly and grow well. Plant several seeds to be sure that at least one comes up. If you have no flower pots use a paper cup to plant the seeds Make a hole in the bottom of the cup and place it in a dish.  It is a good idea to soak the seeds for a day before planting them in earth in the container. This will help the  seeds  to  sprout  Plant  your radish seeds about a half inch down in  the earth. Water the container every day. Grow radish plants for about ). week in two different containers Then stop watering one and keel, watering the other. See what happens.
