To create a pond for your flowers and frogs, score a piece of indium tin oxide-coated plastic (ITO) down the middle with the blade of a pair of scissors, a craft knife turned sideways, or another sharp-but-not-too-sharp tool to create two conductive planes. Use alligator clips to attach one plane to power and one plane to ground of a battery pack.

Place your lotus across the score in the ITO so one LED leg is touching each plane. If it doesn't light up, just turn it around the other way to reverse polarity.

Experiment with different LED colors and even use multiple LEDs in one lotus! Watch what happens when you add a red LED to the mix-- it "hogs" the power since it's easier for electricity to conduct through it than a blue LED.
