The Energy Stick

A toy called the Energy Stick on the market right now is an acrylic stick with colorful LEDs that glow, and a buzzer that plays music when you grab the aluminium on both of its ends. Now let us make a huge Energy Stick that is full of energy with simple materials all by ourselves.

Scientific explanation:

The transistor amplifies the electric current in human bodies which then activates the LEDs and the buzzer. It resembles the Leyden jar that students used to play with but it has a much stronger currency that feels like a real electric shock nobody likes, so the energy stick is much more welcome today.

Other uses:

The energy stick can be used to determine electrolytes, detect an electrical circuit, or touch switch of a home appliance.
