Record voices, music, sounds and use as a buzzer - livens up any game.
These four different coloured buzzers can be used to give a unique sound to each person. Each buzzer measures 9 cm and are great for games that require a speedy response, although there is just as much fun to be had in making the recording. A different and fun present. Not to be used for rude noises, although that can be fun too.
Eleven year old boys are still boys rather than teenagers. A serious outdoor kite makes a great present for an 11 year old, but if they are getting seriously into style, a piece of room decoration might be welcome. Construction kits that involve the opportunity to build cool, outlandish models are popular at this age.
