The term "popsicle sticks" refers to thin, rectangular wooden sticks that are commonly used in crafts and DIY projects. These sticks are typically made from hardwood like maple or birch, and come in various lengths depending on their intended use. They can be easily cut into different shapes using scissors or a saw, making them versatile for creating all sorts of artistic creations such as picture frames, models, and even furniture. The phrase "popsicle sticks" is derived from the popular frozen treat called Popsicles, which were originally sold with wooden sticks back in 1923 to help consumers hold their treats without getting them too messy.
