This super cool glow in the dark putty and UV pen set will amaze you and your friends.
A huge hit in the USA, you can do almost anything with this putty that never dries out. Stretch it, snap it, tear it, shatter it or bounce it - you can even write on it just by pointing with the UV pen provided, like using spray paint. Draw or decorate your putty by simply shining the UV pen onto it and watching your messages or shapes appear in the dark - how awesome is that?
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. Magic is popular and anything involving pranks will appeal to that 9 year old sense of fun. Or get them a great book.
