This teacher decided to conduct an interesting experiment to help his students understand the lesson better and divided the class into two groups. One person from each group had to hold the metal rod of the machine. So one side would carry a positive electric charge and the other a negative one. But don't worry, this current was only a slight tickling sensation. When the students touched their fingers together, the circuit was completed and they felt the slight electric charge on their fingers. You should never try this at home. 👨🔬 (cred: amanbek_uteshkaliev on IG)
