In the corner you can increase and reduce the voltage
Thanks @Zipuu for solving a small bug What is the plasma ball? The plasma ball, also known as a Tesla coil, is an electrical device invented by Nikola Tesla in the late 19th century. It consists of a glass sphere filled with gases and an electrode connected to a high-voltage power source. When activated, it creates an electric field that ionizes the gases, producing mesmerizing plasma discharges. Tesla's contributions to electricity and his inventions continue to inspire scientists and engineers today.
