Use plastic bottles to hold your aquarium plants steady! Cut a large plant into smaller sections and cut a plastic bottle into small rectangular pieces. Punch a hole in the center of each piece of plastic and put the plastic piece onto the bottom of the plant stems. Use a candle or lighter flame to heat the tip of the stem and push it flat against the piece of plastic, set the plants in your tank and cover the plastic plant holders with gravel or stones.
