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.
Nine year olds are clever little fellows and have lots of interests. Great presents for 9 year old boys are remote controlled cars or flying objects, science construction kits, anything that shoots, or outdoor gear. Pranks will appeal to that 9 year old sense of fun. Or get them a great book ideally about football.
