Ideas for 11 and 9 year old boys

[Juanbablo]

My cousins are 11 and 9 and I usually get them a book but would like to get them something a bit different this year. They are lovely boys, very bright and sporty. I was thinking some kind of science kit or craft kit? I don't want to get something too babyish for the 11year old though. Any ideas would be appreciated.

My list I've started of interesting ideas for the boys in my family:

Telescope - stars book
Keepyuppy trainer
Whittling kit
Shuffling machine
Waffle maker

Stickbots

Popcorn maker
Electronics kit (you get to make various things, alarms etc.)
Chemistry set
Football goals

This are things I'm thinking of for my similarly aged boys
Personalised football bootbag
Potato clock
Plasma ball
Praxinsoscope

My nephew is 9. I have got him
beano 'where's wally' style book
beano tricks (fake poo etc)
Build your own robot bug
amazon gift card (for books as we got him a kindle for birthday recently)

I may also get him some football club pj's

My 9yr old is requesting spy gear??! I blame Alex Rider. He's getting door alarms and all kinds of weird gadgets this year. He's also asked for lego, books, and an Xbox360 game. H
e loves getting an Amazon voucher to pick his own too.

What about a game? We love classic monopoly, have bought bean boozle this year.

Thanks everyone, great ideas!

I have just ordered GorillaPod bendy camera-phone tripod things for DS1 and 2 x nephews all aged 11, along with a Pokemon handbook each.

My son will be 9 in February.
This is some of the things he will be getting either for Xmas or birthday.

Modelling clay - I'm buying different types of modelling clay - air dry, lumi Dough and cheap plasticine, with tools and putting in a tub.
Pokemon guide book - a really lovely big book that Amazon were doing for £5 or 3 for a tenner deal.
New Diary of a wimpy kid book (out 1st Nov)
Alex rider book set was £10 in the works.
Lego micro hulk vs Ultron around £6
Ghostbusters slime & figure set £1.99 at Smyths
Lego technic car £17
Minecraft magazine subscription - first 3 issues £1 then £20 for next 6.
I'm making him up a willy wonka sweet hamper, he has been doing the book in school and we recently watched both movies so I have bought wonka sweets like nerds, gobstoppers from poundland and a wonka chocolate bar with golden ticket inside from eBay. Il also be putting other American candy in it maybe with twinkles or similar, a new DVD, a can of juice and I bought from debenhams a giant fizzy cola bottle that's £6. B&m do a hamper with cellophane for £5. But I might just decorate a box to put in.
