1Hello all.. Remove all the toothbrush bristles using pliers (needle-nose would probably work best). Bring a pot of water to a boil, then drop the bristle-free toothbrush into the water. Remove after about 10-seconds, or until the plastic is pliable. It will be HOT, use heat-resistant utensils to protect yourself. Form the toothbrush into your desired shape. Now you have you very own DIY bracelet!
