This electric spark timer (or ticker-tape timer) is a classic piece of physics lab equipment, perfect for demonstrating motion, velocity, and acceleration in the classroom or at home. It works by making tiny sparks at regular intervals onto special paper tape, creating dots that you can measure to analyze movement. The set includes the main timer unit, a clamp (approx. 4.5x1.5x9 cm) to secure it to a desk, a hammer mechanism, and about 160 cm (63 inches) of wire for connection. Overall size is roughly 15x6x4 cm. Made from a mix of iron and durable plastic, it's built to handle student use. The paper tape width is about 1.7 cm. Easy to set up and operate safely with proper supervision. Great for high school or college physics labs, homeschool experiments, or science fair projects. Bring those motion experiments to life with this reliable, accurate timer!
