Stocking for a 10yo

[MinnieMountain]

I was unimpressed with what I found for DS’s stocking last year, so please help.
Aside from foodstuffs (covered) what would be good ideas for a 10yo boy who loves STEM things and Minecraft.
Not Toptrumps. He’s got lots already.

A cool bouncy ball- big ones size of tennis balls. Smyths had a great selection and I got one for teen ds stocking

Rubik's cube - so many different ones now
Fidget spinner
Mini nerf gun
Light prism
Robo alive animal
Voucher for games on his console (if he has one)
Lego technical set - some sell as little as £8
Lego mini figures - Temu do minecraft ones although not official are a bloody good fit and deal.
Hot wheels cars (buy a stunt track for him to build for a Xmas prezzie)
Minecraft hat/ Tshirt

Pocket torch
Fidget toys
Magnifying glass
Slinky
Bath bomb
Age-appropriate puzzle book (eg sudoku or logic puzzles)
Mini gardening kit - eg packets of seeds and mini pots etc.

We always have a second hand book…my 10 year old adores ‘What If’ and its various sequels.

Magic trick
Juggling balls
Pack of playing cards (maybe themed e.g. minecraft?)
Yoyo
Mini voice changer
Sound effects machine
Traditional practical joke stuff e.g. whoopie cushion, fake dog poo
Rubix cube or another puzzle
Mini magic eight ball

Hé sounds similar to my ds13, previous stocking fillers have been:
Minecraft Lego - the small sets
Raspberry pi hats (add ons to build a robot from a mini computer) this is one from this year
Sudoku books
Pop vinyls
This is for ds7 this year:

Ds13 always appreciates Dads Army merch so I’m sure you could find some for his interest
Cd’s - ds13 loves cd’s but there are a bit dated
Vouchers

Minecraft Uno
Joke book
Wallet
Microwave mug cake kit
Magic milk straws

Thank you for the ideas everyone. The stocking feels like more pressure than his presents 😁

moon ball is meant to be fab. Super bouncy and can find it under a fiver sometimes

Can of fizzy drink
Chewing gum
Funky shower gel
Lynx
A book
Key ring
