Small, fun present for a boy of 10?

[GETTINGLIKEMYMOTHER]

A great-nephew I don't often see, and in any case I haven't a clue about what boys that age might like. I give money as well, so a fun present of no more than about £10 - any ideas gratefully received.
I don't want anything 'educational' and books are out since I haven't a clue what he's got. I don't mind if it's 'tat', as long as it's something he'll be pleased with.

You can get cheap and cheerful remote control cars for that price.

fire starter or wire saw go down well for that age. Or a pen knife.. (to be used under supervision obviously)

A maze ball, kept my 9 year old son and my husband and DIL amused for hours!

I've ordered a 'butt head' game that sounds like it fits your description of non educational fun!

UNO ?

My brother bought my dd) 10) a pig popper
Search pig popper on Amazon
She bloody loved it

Head Basketball game is fun and only about £3 in B&M

Many thanks everybody - plenty of ideas for when I go shopping today.

A jar of sweets (make the jar up yourself) with a printed or homemade name label on it.
