Construct your own Buzz Wire and learn how an electric circuit is made. Challenge your friends to move the wand from one end of the wire to the other without making the buzzer sound. Both fun and educational, this kit makes a great rainy day activity and is one of our best selling products. Great Gizmos was established in 1997 and was born out of frustration of having young children and noticing a clear lack of toys out there focusing on what we feel is the important stuff...inspiring children's creativity, expanding their knowledge and building their skills base...whilst having great fun at the same time! Since then we have put all our energies into scouring the world for products that parents want to buy and kids want to play with.
