Toy lights up through a 60+ people! #shorts #DrTatiana #science

This cool toy is known as Steve Spangler's Energy Stick. It has two metallic contacts and if you connect them with an electric conductor, the circuit is closed and the toy lights up. Here Dr. Tatiana made it work through a giant human circuit with dozens of children holding hands! Don't worry, it is completely safe: the toy is powered just by two button batteries and the current is tiny. 👍 LIKE and SUBSCRIBE for more fun science content! ➡️ Follow our channels at https://linktr.ee/tamuphysastr #physics #fyp #tamu #circuit #electrical
