Birthday present 11 year old

[SweetPeaPods]

Niece is 11 this weekend... No idea what to get her. SiL hasn’t been particulay forthcoming with ideas. Apart from vouchers or cash any ideas? I have boys and no idea what 11 year old girls like! She’s very mature for her age, very much a tomboy, into sports but no make up. I only have tomorrow to go shopping so starting to panic!
Thinking maybe a science set but not sure where to start.
Budget £30. TIA

maybe a year's adoption if an animal at a local zoo?

Sports direct vouchers - perhaps alongside a sports bag- or trainers?

Does your brother not have any suggestions? Your best bet might be vouchers. My 10 Yr old loves getting vouchers or her own money to spend.

I think most of a voucher is best at that age, but some of the suggestions above are great too. My DS loves his lava lamp, and neon lights also go down well.

I had to buy a present for an 11 year old girl recently. I asked her mum for suggestions and she said money or an Amazon voucher. It is a difficult age to buy for.

I'd steer clear of toys if she's mature for 11.
What about an active experience? Things like zip wire, indoor skydiving, rock climbing ect. Depends how close you are, you could just give the voucher or you could make it part of a day out with you and your boys or just you.
