Present for 10 year old

[Rosienose]

Grandparents want ideas for a present or combo of presents for 10 year old GS, up to £50. He loves Lego but already has that as main present, any ideas? He doesn’t game.

Hot Wires
Sphero Mini
Smart watch
Robo Kombat
Magic set
Crystal growing kit
3D pen
Build on Brick mug
ThinkFun gravity maze

If he likes lego so he's into construction/kits/building things, then more of that kind of activity or something totally different?

If similar then maybe gravitrax or a building a working robot kind of jam, or a learning to code type kit. If totally different then could be some nice high-quality books, or an oodie, or tickets to a football game, or a skateboard. Anything and everything!

Gravitrax and hot wires have both gone down well here in the past.

My 10yr old would appreciate a Playstation voucher, anything Nike or an experience like a Karting voucher.

Trainers or cinema trip?
