What would be a good present for a 10 YO boy?

[Cuddleczar]

I've only got girls, and they are older now, so I'm completely out of touch with kid's toys. Budget about £10 to £15. I don't know this boy at all so nothing too gender-specific. Any ideas? Need to order it tomorrow...

Nerf gun
Large water pistol
Football
Lego Artic set
Lego Tecnic set
Juggling balls

Venus Fly trap is my present of choice!
Amzaon vouchers
Minecraft T Shirt or baseball cap

Personally I'd opt for money in a card,, my ds is 8 he doesn't really play with toys anymore he asks for football kits and ps3 games which are quite expensive. If you give money he can put it towards something big he wants

My 10 yo would love Lego, Nerf guns as suggested above but would be deeply uninspired by a football or a baseball cap! Just goes to show they are all different, I suppose! He'd also love as many books as you can throw at him, but I appreciate it's not easy to buy books for children you don't know well.

He might like a venus fly-trap, though!

His birthday is approaching and I'm buying him a nice waterproof sports watch. It was going to be his 'big' present but I was amazed at how cheap they were, about £15 on Amazon!

Thanks all, I got a Lego Treehouse in the end, having stalked his mum's FB page and seen mention of Lego!

DS loved the lego treehouse, he still hasn't broken the kit up a year later.

Depends on the 10 y old boy!

DS1 wanted Lego.
DS2 wanted books.
DS3 wanted a smartphone

Money in the card, then he can add it to his pot and buy what he wants when he wants, in this house is usually computer games often bought online to add to the xbox.
