Connect with your friends and light up the world... by just using the power of touch! Just touch both metal ends yourself or with a ring of people holding hands to create forks of lightning and buzzing sounds within the tube. the principle is really simple. the energy stick has a highly sensitive circuit that's able to detect very small amounts of electricity that travel across your skin. in order for the energy stick to activate, each of the two foil ends must be connected by something that allows electrons to flow through it. this will work with an infinite amount of people as long as they link hands and is completely safe! Comes in a try-me gift box.features- recommended age: 6+product information- product: funtime energy stick- material: plastic- dimensions: l 17.1 x ø 3 cm- colour: black- packaging: gift packaging- packaging dimensions: l 22.5 x w 8 x h 4.5 cm - packaging weight: 105 grams- brand: funtime
